The Python Imag­ing Library, PIL, is a very use­ful addi­tion to your Python instal­la­tion if you need to manip­u­late pic­tures. Django uses it to val­i­date upload images for example.

On a Mac you do need to install lib­jpeg beforehand.

Install lib­jpeg:

• Get the source: http://www.ijg.org/files/jpegsrc.v6b.tar.gz

• Extract the archive.

• Move inside the source direc­tory and exe­cute the fol­low­ing commands:

  cp /usr/share/libtool/config.sub .
  cp /usr/share/libtool/config.guess .
  ./configure --enable-shared
  make
  sudo mkdir -p /usr/local/include
  sudo mkdir -p /usr/local/bin
  sudo mkdir -p /usr/local/lib
  sudo mkdir -p /usr/local/man/man1
  sudo make install
  

Install PIL:

• Get PIL at: http://effbot.org/downloads/Imaging-1.1.6.tar.gz

• Extract the archive.

• Move inside the source directory

• Change the fol­low­ing val­ues in setup.py from the default None to:

  JPEG_ROOT = "/usr/local/include"
  ZLIB_ROOT = "/usr/local/include"
  

• Check if every­thing is well configured:

  python setup.py build_ext -i
  python selftest.py
  

• If no errors are found and the required libraries are installed (like JPEG sup­port), install PIL:

  sudo python setup.py install
  

And that’s it, I’ve tried this on Mac OS Leop­ard, and it works fine, let me know how it went for you.
