+++ This bug was initially created as a clone of Bug #977394 +++ Description of problem: Developer Toolset v2.0 beta currently requires the user to subscribe to the Optional channel solely for the mpfr-devel package, which is a dependency for DTS v2.0 gcc. Please move mpfr-devel to primary Server/Workstation channels for 6.5/5.10 to remove this extra step for DTS users.
Streams required: RHEL5: 5.9, 5.10+ RHEL6: 6.2, 6.3, 6.4, 6.5+ RHEL7: 7.0
Package mpfr_devel isn't in RHEL 5 at all.
