I’ve found inconstancy between output of repoquery and rpm. I was looking forward towards apache php 5.4 module which must provided by some package SCL (can someone tell me?).
rpm -qf /etc/httpd/modules/mod_proxy.so httpd-2.2.15-29.el6.CentOS.x86_64
repoquery -qf /etc/httpd/modules/mod_proxy.so
so repoquery results in no output
yum list installed httpd Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile
Installed Packages httpd.x86_64 2.2.15-29.el6.CentOS @c6-media
repoquery -qa httpd httpd-0:2.2.15-29.el6.CentOS.x86_64
No wonder libphp5.so results in no output.
