Hmm, what exactly was the problem?

Some time ago I actually tested a gtk based application and it worked.
Just for fun I build xli from pkgsrc last night:

/usr/X11R6/bin/xli:
         -lX11.6 => /usr/X11R6/lib/libX11.so.6
         -lXext.6 => /usr/X11R6/lib/libXext.so.6
         -lz.0 => /usr/lib/libz.so.0
         -lm.0 => /usr/lib/libm.so.0
         -lpng.3 => /usr/pkg/lib/libpng.so.3
         -lc.12 => /usr/lib/libc.so.12

and it displays all the test pictures I tried without problems.
