Hi folks --

Further to Bill's remarks below about the MESA SDK:

I put out a new release of the SDK just now (see the link above), which brings the 'current' version to 20111212 (Dec 12, 2011). Together with a number of minor tweaks, this version should resolve some issues that have arisen when linking against the PNG library (libpng).

It turns out there are fundamental incompatibilities between libpng v1.2 and v1.4, leading to missing symbol errors on some systems. To fix this problem, I've built the whole of libpng into the PGPLOT library (libpgplot), so the system libpng is no longer accessed. I've verified that this works on at least one Linux x86_64 box (thanks, Ben Brown!); please let me know if you encounter any more missing PNG-related symbols.
