Syntax error when installing the spkg package of wxPython on Sage

Question

When I want to install the package wxPython-2.8.7.1.spkg from here

in the terminal of Sage it gives me a syntax error. What i write in Sage terminal and the result are as follow:

sage: sage -i wxPython-2.8.7.1.spkg
------------------------------------------------------------
   File "<ipython console>", line 1
     sage -i wxPython-RealNumber('2.8').gen(7).1.spkg
                    ^
SyntaxError: invalid syntax

I also use the direct address of the package but the result was the same:

 sage: sage -i http://www.sagemath.org/packages/experimental/wxPython-2.8.7.1.s>
------------------------------------------------------------
   File "<ipython console>", line 1
     sage -i http://www.sagemath.org/packages/experimental/wxPython-RealNumber('2.8').gen(7).1.spkg
                ^
SyntaxError: invalid syntax

I also downloaded the package and used the local address but the result was the same.

You need to do this from the command line before starting Sage. Otherwise you can use

sage: install_package("wxPython")

which is currently downloading for me... and then failed:

checking for GTK+ - version >= 2.0.0... no
*** Could not run GTK+ test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GTK+ is incorrectly installed.
configure: error:
The development files for GTK+ were not found. For GTK+ 2, please
ensure that pkg-config is in the path and that gtk+-2.0.pc is
installed. For GTK+ 1.2 please check that gtk-config is in the path,
and that the version is 1.2.3 or above. Also check that the
libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config
--libs' are in the LD_LIBRARY_PATH or equivalent.

Along those lines, here is what it says at the list of experimental spkgs, of which this is one:

These are EXPERIMENTAL! They probably won't work at all for you! Use at your own risk! Many of these have never been successfully built on any platform!

So buyer beware!

Though in this case it does give you some ideas for how you might fix it. "Optional" spkgs should install fine on all supported platforms. — kcrisman, Jun 27 '12 at 15:36
