e.g.  actual error report is '...

libpng error: Application must be recompiled; version 1.0.6 was
incompatible

Error: pdflatex (file calmodulin.png): png_create_read_struct() failed

...'   The same files work on an identical machine running RedHat 6.2

It should be sufficient a tetex-pdflatex recompile. Due to the quite
big work involved, could someone do it at RH and put an update out? 
I think this could well be marked as a critical bug (if you need pdflatex). 

By the way. Shouldn't incompatible API changes on dynamic library 
bumps the mayor revision number?

Well, I think I solved it. 
It's not a problem of just recompilation: there is a bug in the tetex
source package. In spite of being configured with --with-system-pnglib, 
there are object files compiled against it's internal libpng header files.

What I did is to add this hack to the spec file: 
******

+++ tetex-r.spec        Mon Dec  4 08:46:35 2000

*****

I made available the spec-file and the recompiled rpms at 
http://usuarios.tripod.es/r_mano/linux/

I added a R to the release (I am not official related to RH, so I did 
not feel in the right to bump the build number, especially with a so 
ugly hack).

Fixed (by the hack you've suggested) in tetex-1.0.7-10. Thanks *very* much for
submitting
a fix.
