Fink only supports manual intervention via changes to the package
description (.info) and specified patch files.
I tried to do something comparatively simple and use Fink's "flag-sort"
tool to change the order of compiler flags, but that appears possibly to
change the order _too_ much and produces a failure later on in the build:
flag-sort -r clang -L/sw/lib -bundle -L/sw/lib/python2.7/config
-lpython2.7 -L/sw/lib -L/sw/lib/freetype219/lib
-L/sw/lib/fontconfig2/lib -I/sw/include/pygtk-2.0
