evolution-2.0.2-16.src.rpm

Description of problem:

evolution has an implicit build dependency on the mozilla package which version
is listed in %define mozilla_build_version x.x.x. However down in BuildRequies
it says

BuildRequires: mozilla-nspr-devel >= 37:%{mozilla_build_version}
BuildRequires: mozilla-nss-devel  >= 37:%{mozilla_build_version}

This means that if mozilla is updated to a next version evolution build will
start but then fail because of 

if [ ! -f /usr/include/mozilla-%{mozilla_build_version}/nspr/nspr.h ]; then
  echo "Unable to find suitable version of mozilla nss to use!"
  exit 1

The spec file must be made flexible enough to avoid the conflict.
