The ultimate cause of this issue was an upgrade of glib2 by RedHat in RHEL 7.1. And because the glib2 library does not use symbol versioning, rpm cannot automatically add the proper requires/provides to avoid installing incompatible libraries. So, this has nothing to do with EPEL, per se, but just normal issues that can occur with any update to RHEL. Thanks for the heads up though. I suspect many other glib2 using libraries may be affected as more epel updates come out. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane [email protected] Boulder, CO 80301 http://www.nwra.com
