libpng 1.0.2 woes

I'm having some questions regarding libpng 1.0.2. While imlib and Emusic wont compile with libpng 1.0.2. XEmacs 21.2.5 wants libpng 1.0.2. I was said that imlib and Emusic don't compile with 1.0.2 because this version is somewhat buggy. So I installed libpng 1.0.1. Now I have to force XEmacs to ompile with is. Now I'm confused. What this all about the different versions of libpng? Regards Martin -- A LISP programmer knows the value of everything, but the cost of nothing. -- Alan Perlis
