There are. However they would not recommend to replace the old PCRE with newer
one. At least because they are not compatible. You could end up with
unbootable system.
If you need a spec file for a newer PCRE, you can get one from Fedora
distribution <
http://pkgs.fedoraproject.org/cgit/pcre.git/>. However I doubt
an unmodified recent spec file will get buildable on such ancient system like
RHEL 4. To get more details about packaging software into an RPM, read
<
http://fedoraproject.org/wiki/How_to_create_an_RPM_package>.
I guess you will need to modify the ./configure invocation to install the new
PCRE into different directories not to conflict with the system one. If you
are not familiar with building from sources, you should hire somebody who is.
