The compiler errors come again from the setjmp check in pngconf.h:

           __pngconf.h__ in libpng already includes setjmp.h;
           __dont__ include it again.;

The buildbot runs Debian Lenny which includes an old version of libpng.
That version does not use PNG_SKIP_SETJMP_CHECK to skip the setjmp check.
Defining PNG_SETJMP_NOT_SUPPORTED might help with this
version, but I still have to test that.

Updating the buildbot to Debian Squeeze would also work.

Cheers,
Stefan
