Description of problem:
To build the rpm, 'libpng-devel' is needed. The rpm libpng-devel provides this but also libpng10-devel provides this:

[dries@delirium dries]$ rpm -q --provides libpng10-devel
libpng-devel = 1.0.13
libpng10-devel = 1.0.13-9

When libpng10-devel is installed and libpng-devel is not installed, the build halts in ./configure. Reason: one of the first tests in configure is a check if gcc is able to compile something. The spec file contains the line
LIBS="-lfreetype -lpng -ljpeg -lz -lnsl"; export LIBS
So the small test in the configure fails when libpng-devel is not installed.

When you remove the libpng10-devel and install libpng-devel, the rpmbuild works without problems.




Version-Release number of selected component (if applicable):
php-4.3.3-6, libpng10-devel

How reproducible:
Always

Steps to Reproduce:
1. make sure libpng-devel is not installed
2. make sure libpng10-devel is installed
3. try to rebuild the php source rpm
    

Actual Results:  Build fails

Expected Results:  A lot of php rpms in my RPMS directory :-)

Additional info:

interesting part in the config.log when libpng10-devel is installed and libpng-devel is not installed:
