##### Python linking on OS X is tricky ###
# Confounding problems are:
# 1) likelyhood of multiple python installs of the same major.minor version
# because apple supplies python built-in and many users may have installed
# further versions using macports
# 2) boost python directly links to a python version
# 3) the below will directly link _mapnik.so to a python version
# 4) _mapnik.so must link to the same python lib as boost_python.dylib otherwise
# python will Abort with a Version Mismatch error.
# See http://trac.mapnik.org/ticket/453 for the seeds of a better approach
# for now we offer control over method of direct linking...
# The default below is to link against the python dylib in the form of
#/path/to/Python.framework/Python instead of -lpython
# http://developer.apple.com/mac/library/DOCUMENTATION/Darwin/Reference/ManPages/man1/ld.1.html
