The package you are having a problem with has a .rf in the name ... that
means it is a package from the repoforge repo.

You might make sure the rpms are installed properly so that the rpm
database knows it exists (and it is not orphaned at the location).  What
does this return:

rpm -q --whatprovides /usr/lib/libxerces-c.so.27

also, download the file xerces-c-2.8.0-1.el5.centos.i386.rpm what does
this say:

rpm -qpl xerces-c-2.8.0-1.el5.centos.i386.rpm

It would seem that xerces-c-2.8.0-1.el5.centos.i386.rpm is going to
upgrade the library to /usr/lib/libxerces-c.so.28 to me.

This is going to cause an issue with that repoforge package.  You can
use exclude= for the extras repo, ask repoforge to rebuild the package
against the new version, or probably force install the rpm and symlink
/usr/lib/libxerces-c.so.28 to /usr/lib/libxerces-c.so.27 and see if it
