apache upgrade problem

I am running red hat enterprise ES, fully patched, with the latest kernel. I know just enough about linux to be dangerous. I am trying to upgrade the version of apache that was installed with redhat (2.0.46) to 2.0.48.

This "upgrade" process isn't working very well. I tried what is listed in the apache 2.0 documentation - downloading the source tarball from their site, unpacking, ./configure --enable-so (so php will work), make, make install. This puts apache in /usr/local/apache2 (new dir) - when I start from bin/apachectl start and then check to see what version of apache I'm running, it's 2.0.46.

I was a little frustrated, so deleted the /apache2 dir and recompiled the source with --enable-so and --prefix=/var/www (where it looked like apache was installed before). same results - when i start apache, it's 2.0.46.

Any suggestions on how to make this upgrade bit work?

There is an rpm loaded - httpd-2.0.46.ent.i386.rpm. When I try to remove it "rpm -e httpdblahblah.rpm" it says rpm package not installed.

Thanks in advance...

P.S. the webserver is running great as .46 - even after the botched apache upgrade. and it's playing nice with php and mysqld...
