Nothing comes to mind right away except maybe the png and zlib header
files in the ldglite zip file might conflict with whatever versions you've
actually got installed. I originally put them there for the windows build
and have been meaning to move them out of the way into a subdirectory only
used by the windows makefile. Try moving (or removing) z*.h, png*.h, and
*.a from the ldglite directory and rebuilding.
If that doesn't work it's usually pretty easy to debug a core dump of
a segfault. Just look for the bad pointer.
