(Forgive me, I read the digest. Cc me on replies if you want.)
I've added further comments to the releng thread:
https://fedorahosted.org/rel-eng/ticket/3815
It looks to me like the core problem is the tcl Provides line that defines
the tcl(abi) to be the exact same as the full version. Given that the name
of the lib is libtcl8.5, the ABI designator probably should include the the
patch level (.7 or .8).
That would solve the death-grip between tcl and dependent packages. But
that's possibly something that needs to be done in rawhide (and tracked with
a bug).
