Hi,
This is a simple but very "funny" problem I'd just like to report.
This has to do with the pcre package.
I upgraded an SL 5.0 server to 5.1. I needed to install pcre-devel, so using yum:
# yum -y install pcre-devel
Loading "kernel-module" plugin
Setting up Install Process
Setting up repositories
Reading repository metadata in from local files
Parsing package install arguments

Ok, so what do I have installed:
# yum list pcre\*
Loading "kernel-module" plugin
Setting up repositories
Reading repository metadata in from local files
Installed Packages
pcre.x86_64 6.6-2.el5.7 installed
pcre.i386 6.6-2.el5.7 installed

pcre-devel.i386 6.6-2.el5_1.7 sl-base
Ok, so I try to install from the SL5.1 tree manually:
# rpm -Uvh

Preparing... ########################################### [100%]
package pcre-6.6-2.el5.7 (which is newer than pcre-6.6-2.el5_1.7) is
already installed
ie. I cannot install pcre-devel 6.6-2.el5.7 because that only exists in the SL
5.0 security area:
http://ftp.scientificlinux.org/linux/scientific/50/x86_64/updates/security/
and is not in 5.1 or in 5.2, and the pcre I have running in SL5.1 is actually
not what it should be running (or not what SL5.1 or 5.2 is supposed to have
installed), but the newer pcre from SL 5.0
When I upgraded using yum from 5.0 to 5.1, the pcre wasn't "downgraded" to the
older pcre-6.6-2.el5_1.7 in SL5.1
To resolve this, I just did:
# rpm -Uvh
http://ftp.scientificlinux.org/linux/scientific/50/x86_64/updates/security/pcre-devel-6.6-2.el5.7.x86_64.rpmhttp://ftp.scientificlinux.org/linux/scientific/50/x86_64/updates/security/pcre-devel-6.6-2.el5.7.i386.rpm

ie. installed the pcre-devel from SL 5.0 into the 5.1 environment.
