I'm sure it does.

Red Hat 7.2 ships with libpng 1.0.12. So it seems that hobbitgraph.cgi
picks up the standard libpng 1.0 run-time library - try doing a
"ldd ~hobbit/server/bin/hobbitgraph.cgi" and see what libraries
it picks up.

But your system has the header files - /usr/include/png.h et al - 
from another libpng version, 1.2.8. This mismatch between the
header-files (used when compiling Hobbit) and the run-time library
is what triggers this error.

Which libpng version did you compile, then ? And you need to check all
of the /usr/lib/libpng.so* files, since those are the ones used at
run-time. Did you also run "ldconfig" to update the cache of runtime
libraries ?
