My guess is that you have included the EPEL repo (<a href="http://dl.fedoraproject.org/pub/epel/5/" target="_blank">http://dl.fedoraproject.org/<u></u>pub/epel/5/</a>) in your enabled repos.<br>
<br>
The version of R available from EPEL 5 is R-3.1.0.el5, but the LON-CAPA CentOS 5 repository (<a href="http://install.loncapa.org" target="_blank">http://install.loncapa.org</a>) has R-2.13.0-1.el5.<br>
<br>
Packages such as R-quadprog available from the LON-CAPA CentOS 5 repo were built against this older version of R.<br>
<br>
When time allows (in the near future) I will look into building updated R-* packages against R-3.1.0, and testing with LON-CAPA 2.11.0.<br>
<br>
If my diagnosis is correct, then one solution for you for now would be to:<br>
<br>
(a) temporarily disable use of the epel repo<br>
(b) use:<br>
<br>
yum remove R-core<br>
<br>
to remove R, R-core, and the other R-* packages, as well as the LONCAPA-prerequisites rpm<br>
<br>
(c) do:<br>
yum install LONCAPA-prerequisites<br>
<br>
to re-install R, R-core etc. and the LONCAPA-prerequisites rpm from the LON-CAPA CentOS 5 repo<br>
<br>
(d) re-enable the epel repo<br>
(e) temporarily block update of R and R-core by adding:<br>
<br>
exclude=R,R-core<br>
<br>
to /etc/yum.conf<br>
<br>
Once I have updated the LON-CAPA CentOS repo with newer R-* packages built against R-3.1.0 you should remove the line: exclude=R,R-core<br>

When trying to patch our machines, they fail with "Missing Dependency:<br>
libRblas.so is needed by package R-quadprog-1.4.12-0.centos5.<u></u>lc.i386<br>
(loncapa-updates-basearch)"<br>
<br>
If you look for the library it's there, but it seems there's something<br>
wrong with either the yum database or the package itself. Cleaning caches<br>
doesn't help. Any ideas?<br>
<br>
Thanks,<br>
