Yep, the link is there.

You probably did this already, but I'm going to mention it -

Well, I didn't actually, I'm not that knowledgeable on the linking process
(physicist
turned CS researcher, you know, learning as a go along :-) ). The result is
bizarre:

nm: /usr/lib/libpng.so: no symbols

No symbols? Does this mean the lib is broken? There are quite a lot libs in
/usr/lib
which return the same result. The only other lib I've installed locally
which has libpng
linked in is Qt4, but I haven't tried that out yet, aside from running the
demos, so I can't
really tell whether it works or not. Any common tools which need libpng to
work? Xv, Gimp?
If I know for certain it doesn't work, I'll pester our sysadmin about it.

As a final desperate act, install libpng from source in a new directory
> and try linking to it (using MPLIB_BASE).


I'll try that, thanks for the help, I appreciate it.
