Hi Alex,
This is really strange. Are you sure all libpng links are correct?
Matplotlib will link only to a name libpng.so, so you need this link.
Yep, the link is there.
You probably did this already, but I’m going to mention it -
check if the library has the missing symbol:nm /usr/lib/libpng.so | grep png_set_sBIT
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.
