Pymacs

get pymacs here: http://pymacs.progiciels-bpi.ca/archives/Pymacs-0.22.tar.gz

 tar xvzf Pymacs-0.22.tar.gz
 cd Pymacs-0.22

now, because of some not-allowed characters, you have to remove the following two lines

 # Fran?ois Pinard <pinard@iro.umontreal.ca>, 2001.
 #!/usr/bin/env python

from the files

 Pymacs/__init__.py
 Pymacs/pymacs.py

now, you can compile and install:

 python setup.py install
 sudo ln -s /Library/Frameworks/Python.framework/Versions/Current/bin/pymacs-services /usr/local/bin/
