libpng compiles and works fine on FreeBSD but libpng-config returns the
wrong information
arran:[1141] libpng-config --cflags
-I/usr/local/usr/local/include/libpng -DPNG_USE_PNGGCCRD -O2 -fno-strict-aliasing -pipe
arran:[1142] libpng-config --ldflags
-L/usr/local/usr/local/lib -lpng -lz -lm
arran:[1145] libpng-config --I_opts
-I/usr/local/usr/local/include/libpng
This bug is due to adding PREFIX twice to these variables:
arran:[1053] diff makefile.freebsd.orig makefile.freebsd
15,16c15
< DESTDIR= ${PREFIX}
< LIBDIR= /lib
---
> LIBDIR= ${PREFIX}/lib

You can either remove the PREFIX in the top lines or the bottom lines.
Since it appears necessary for the top lines, I believe the proper patch is
this:
