[ a few tests later ... ]
It is not possible to use Provides: tetex without a version number,
because :
coreutils conflicts tetex < 1.0.7-66
Using :
Provides: tetex = %{version}
Obsoletes: tetex
doesn't make any change, rpm install texlive without removing tetex.
I have also tried Conflicts: but it doesn't work :
Provides: tetex = %{version}
Conflicts: tetex < %{version}
--> Running transaction check

---> Package texlive-texmf.noarch 0:20110312-0phn set to be updated
--> Processing Conflict: texlive conflicts tetex < 20110312
The version of tetex is :
$ rpm -q --qf '%{epoch}-%{version}-%{release}\n' tetex
(none)-3.0-33.8.el5_5.6
and texlive :
(none)-20110312-0phn
so, if I understand correctly, the tetex provided by texlive
should be "newer" than the real tetex ?
