Hi Eva,
I bet it stems from us having a epoch of 2 in our version of R.
That stems back from the first time we compiled R, I didn't see that we had
an epoch of 2. I didn't notice that we had the epoch until I was reading the
spec file from Fedora or EPEL, which has the epoch in, with a note saying
they had to do it because Scientific Linux had it. Once you have an epoch,
it's almost impossible to get it out.
But how to fix your problem?
You need to exclude R that is coming from Scientific Linux. That's not too
hard. You need to add the following at the end of /etc/yum.repos.d/sl.repo
and /etc/yum.repos.d/sl-security.repo
exclude=R R-devel libRmath libRmath-devel
That should keep it from trying to install Scientific Linux's R.
I have a horrible feeling that the epoch=2 evil might well be my fault.
The changelog in the sl53 (R-2.8.1) specfile contains:
* Fri Feb 08 2008 Jon Peatfield <[email protected]> - 2:2.6.2-1
- Update to 2.6.2 tweaks to build on SL5x (and add DAMTP evil hacks in
a slightly cleaner way). Include fix from SL5x 2.5.0-2 srpm (zip
must be a BuildRequires or it won't get listed in etc/Renviron when
built in brewbuilder). Epoch needs to be 2 for SL5x.
...
before that all the epoch numbers mentioned seem to be 1...
If I did cause this mess then I'm sorry for all the trouble is has caused.
In any case I wonder it it would be worth us asking (nicely) if the CRAN
people would set epoch=2 on their rhel5 rpm builds since otherwise anyone
using EPEL on RHEL/SL/CENTOS will be unable to directly use the CRAN
version...
