Adding a prereq to an rpm?

[Bill Woodward <wpwood dazel com>]

OK, here's my stupid question du jour.  I am working on an installation
scheme for a system to do a Redhat kickstart install and install a
number of RPMs.  Two of the RPMs are the apache web server and
ApacheJServ (the mod_jserv module).  The problem is that although
ApacheJServ requires apache, it is not a prereq, so it's possible that
ApacheJServ will be installed before apache is installed.  This screws
up the ApacheJServ postinstall script, which updates the apache
httpd.conf.

So, it there any way to add a prereq to an existing RPM?  Or a way to
tell the kickstart install to install one RPM after another?  I suppose
that I could create my own apachejserv.spec file with an apache prereq,
run rpm2cpio on the rpm, unpack all of the files, and then create a new
RPM, but that seems (ahem) just a tad kludgy.

Any suggestions?

TIA,
- Bill
