>Description:
The mapserver port makefile has a config knob "[ ] PDF      Support for PDF output via pdflib"

If built with this option enabled, the mapserver applications will crash any time they attempt to open a PNG file.

This appears to be caused by conflicts between pdflib's builtin PNG library and /usr/local/lib/libpng.so.6 which is loaded by the mapserver programs. In any case, building w/o the PDF knob checked solves the problem.
>How-To-Repeat:
% cd /usr/ports/graphics/mapserver
% make config

[check the option for Support for PDF output via pdflib]

% make all

% cd /usr/ports/graphics/mapserver/work/mapserver-5.6.4
% ./shp2img -m tests/test.map -o test.png

the above is the test suggested in tests/README
[watch it fail]
