I'm trying to build a patched version of the firefox-31.1.0-6.el5.src.rpm package for EL5, and am getting the following missing deps:
DEBUG util.py:283: Error: No Package found for hunspell-devel DEBUG util.py:283: Error: No Package found for libvpx-devel >= 1.3.0 DEBUG util.py:283: Error: No Package found for system-bookmarks
And indeed I cannot find any of those packages at http://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/ (or 5client). I realize this is more of an upstream issue, but was hoping somebody here would have some insight from trying to build that for CentOS.
