# the "perl Makefile.PL" method fails to build the shared library,
# probably it's obsolete and the author forgot to remove Makefile.PL
# from the tarball.

# you might notice this in the build log:
# ** WARNING: found gd.h header file in /usr/X11R6/include/gd.h
# this isn't a real issue, since on Slackware /usr/X11R6/include
# is just a symlink to /usr/include.

# one of the tests in t/GD.t fails because it's using freetype to render
# text into images, then comparing pixel-for-pixel to reference images. it
# fails because the results are not pixel-exact, probably due to the
# author using a different version of freetype to generate the reference
# images... or even just different compiler flags used for building
# freetype... or even something as dumb as using a different CPU whose
# floating point returns slightly different results from the author's.
# if you modify the test code so it writes its result to a PNG file and
# then eyeball that next to the reference one (t/test_data/t07/7-00.png),
# you'll be hard-pressed to see the difference... but it's there.

# this patch disables just this one test:
patch -p1 < $CWD/no_ttf_test.diff
