It is not a license issue .. it a RHEL choice.  And a policy.  Red Hat
does not maintain these packages audited in a "released" state for the
binaries.  The do release the source code for these packages and one can
build it themselves if they want the packages.

The issue is, these are for linking and not for release.

(I have nothing to do with there decisions :D )
