Leopard

This will not compile directly on Leopard. You will need to change line 14 of Authorization.pxi from "raise" to "raise _err".

The following shows a concrete example for using this with Leopard.

# This has been tested on a Mac OS X 10.5.5 Leopard stock Python installation
# on October 25, 2008

# The following is sufficient for using Pyrex, 
# it doesn't need to be installed
export PATH=$HOME/Downloads/Pyrex-0.9.8.5:$PATH
export PYTHONPATH=$HOME/Downloads/Pyrex-0.9.8.5:$PYTHONPATH

cd $HOME/Downloads/Authorization-0.1

# Solve "Use __cinit__ instead"
perl -pi -e  's/__new__/__cinit__/g' ./src/Authorization.pxi

# Solve "Reraise not inside except clause"
perl -pi -e 's/raise /#raise /g' ./src/Authorization.pxi

# Compile, but do not install
python ./setup.py build_ext --inplace

# Solve "cannot import name kAuthorizationFlagDestroyRights"
perl -pi -e  's/, kAuthorizationFlagDestroyRights//g' ./test/test.py
perl -pi -e  's/destroyflags=\(kAuthorizationFlagDestroyRights,\)//g' ./test/test.py

# Test
export PYTHONPATH=./lib/:$PYTHONPATH
python test/test.py

# should give:
# I'm root!
