In the process of trying to write a Python script that uses PIL today, I discovered I don't seem have it on my local machine (OS X 10.5.8, default 2.5 Python install).
So I run:
easy_install --prefix=/usr/local/python/ pil
and it complains a little about /usr/local/python/lib/python2.5/site-packages not yet existing, so I create it, and try again, and get this:
TEST FAILED: /usr/local/python//lib/python2.5/site-packages does NOT support .pth files error: bad install directory or PYTHONPATH
You are attempting to install a package to a directory that is not on PYTHONPATH and which Python does not read ".pth" files from. The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was:
/usr/local/python//lib/python2.5/site-packagesand your PYTHONPATH environment variable currently contains:
''
OK, fair enough -- I hadn't done anything to set the path. So I add a quick line to ~/.bash_profile:
PYTHONPATH="$PYTHONPATH:/usr/local/python/lib/python2.5"
and source it, and try again.
Same error message.
This is kindof curious, given that PYTHONPATH is clearly set; I can echo $PYTHONPATH and get back :/usr/local/python/lib/python2.5. I decided to check out what the include path looked like from inside:
import sys
print "\n".join(sys.path)
which yields:
/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python25.zip /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5 /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-darwin /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-mac /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/plat-mac/lib-scriptpackages /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-tk /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload /Library/Python/2.5/site-packages /System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/PyObjC
from which /usr/local/python/yadda/yadda is notably missing.
Not sure what I'm supposed to do here. How do I get python to recognize this location as an include path?
UPDATE
As Sven Marnach suggested, I was neglecting to export PYTHONPATH. I've corrected that problem, and now see it show up when I print out sys.path from within Python. However, I still got the TEST FAILED error message I mentioned above, just with my new PYTHONPATH environment variable.
So, I tried changing it from /usr/local/python/lib/python2.5 to /usr/local/python/lib/python2.5/site-packages, exporting, and running the same easy_install command again. This leads to an all new result that at first looked like success (but isn't):

PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version 1.1.7
platform darwin 2.5.1 (r251:54863, Sep 1 2010, 22:03:14)
[GCC 4.0.1 (Apple Inc. build 5465)]

--- TKINTER support available
--- JPEG support available
--- ZLIB (PNG/ZIP) support available
*** FREETYPE2 support not available
*** LITTLECMS support not available
--------------------------------------------------------------------
To add a missing option, make sure you have the required
library, and set the corresponding ROOT variable in the
setup.py script.
To check the build, run the selftest.py script.
zip_safe flag not set; analyzing archive contents...
Image: module references __file__
No eggs found in /var/folders/XW/XWpClVq7EpSB37BV3zTo+++++TI/-Tmp-/easy_install-krj9oR/PIL-1.1.7/egg-dist-tmp--Pyauy (setup script problem?)
Again, this looks good, but when I go to run my script:
Traceback (most recent call last):
File "checkerboard.py", line 1, in import Image, ImageDraw ImportError: No module named Image
When I check what's now under /usr/local/python/ using find ., I get:
./lib ./lib/python2.5 ./lib/python2.5/site-packages ./lib/python2.5/site-packages/site.py ./lib/python2.5/site-packages/site.pyc
So... nothing module-looking (I'm assuming site.py and site.pyc are metadata or helper scripts). Where did the install go?
I note this:
To check the build, run the selftest.py script.
But don't really know what that is.
And I also noticed the "No eggs found" message. Are either of these hints?
