Description René Gabriëls 2010-05-24 19:58:07 UTC

povray checks the libpng version during configure: it required a version < 1.4, which is not installed currently.  Even installing libpng:1.2 manualy doesn't work, presumably because pkgconfig only knows about version 1.4.

Reproducible: Always

Steps to Reproduce:
1. emerge povray

Actual Results:  
fails.

Expected Results:  
should compile fine.

The now deleted _beta32 was fine with libpng 1.4, seems upstream added some retarded logic into _beta35:

checking for libpng version >= 1.2.5... 1.4.2, ok
checking for libpng version < 1.4 (not supported at the moment!)... bad
configure: error: cannot find a suitable PNG library

This needs to be patched out of the configure script, and please, if you plan on adding new packages into ~arch with libpng in *DEPEND string, really test it before committing...

Pardon the goof (my bad) - I did not have libpng 1.4 installed when testing.

I have disabled this logic, but I am concerned there may be a real reason for it.  PNGs seem to write OK, however.
