[ome-users] compile error

[Ilya Goldberg]

Hi
What version of libpng are you using?
Are you sure that when you installed it from source, the OS loaded  
the right lib (ie, is your libpng picked up by ldconfig?).

I am not aware of incompatibilities introduced by later versions of  
libpng, but that may be the case here.
Versions in use here are 1.2.2, 1.2.5, 1.2.8 - all using the relevant  
RPMs on Fedora
