[Discuss] perl/Tk

[Bill Ricker]

This is likely caused by a miss-match of binary and headers or flags
for libpng.a .
Looks like specifically png_init_mmx_flags is missing in link, so I'm
thinking one was built for modern processor and one for older/portable
x86.

You may need to diagnose what headers and IFDEFs  were included in
compile of pngtst.c.

[ Normally I'd say bring Perl questions to the Boston.pm.org mailing
list, but this really is a C/Linux question.]
