# TODO:
# 1) When the Python build fails due to missing openpty, it needs to be linked
# with: -ldl -lpthread -lutil
# (see http://root.cern.ch/root/roottalk/roottalk11/1344.html)
# The solution probably is to link with libpython.so instead of libpython.a
#
# 2) The vtk libraries must be moved from $SPKG_LOCAL/lib/vtk-5.10/* to
# $SPKG_LOCAL/lib/*
