Difficult installing R package pdftools

Question

I am trying to install R package “pdftools” and encounter the following:

In file included from libqpdf/Pl_DCT.cc:1:
include/qpdf/Pl_DCT.hh:27:10: fatal error: 'jpeglib.h' file not found
#include <jpeglib.h>
         ^
1 error generated.
make: *** [libqpdf/Pl_DCT.o] Error 1
ERROR: compilation failed for package ‘qpdf’

I am using R version 3.3.3 on a mac with OS X 10.10.5 and can’t update my OS at the moment for a number of reasons.

1. I verified that the downloaded source packages are in: /private/var/folders/t3/_mlp_5z15z9_628n5q00pw_s8d_kfs/T/RtmpnJERsz/downloaded_packages

2. I saw the following post: 'jpeglib.h' file not found

And ran

$ find /usr/local -name \*jpeg\* -print -name \*jpg\* -print
/usr/local/Cellar/boost/1.71.0/include/boost/gil/extension/io/jpeg
/usr/local/Cellar/boost/1.71.0/include/boost/gil/extension/io/jpeg.hpp

/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/mjpegtools.rb
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/mozjpeg.rb
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/openjpeg.rb
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/recoverjpeg.rb
find: /usr/local/jamf: Permission denied

The file "jpeglib.h" does not seem to be listed, but I located it in: /anaconda3/pkgs/jpeg-9b-he5867d9_2/include/jpeglib.h

3. Based on other posts, I tried from terminal:

$ brew install boost. (Lot of installing, no errors)
$ brew doctor (Lot of installing, no errors)
$ xcode-select: error: command line tools are already installed, use "Software Update" to install updates
$ brew install cairo gobject-introspection pixman (Lot of installing, no errors)

Then rebooted and tried installing pdftools again with same result.

4. Also saw this post but it was completely over my head: https://www.cocoanetics.com/2012/01/helping-xcode-find-library-headers/

Any solutions in simple steps appreciated.
