Going back to an earlier post on this subject. I've made some progress and was able to get rpmbuild -bp php.spec to run. So now I have a patched php-4.2.2 under /usr/src/redhat/BUILD. So I can do a configure/make/make install.

Now my concern before proceeding is how this is going to impact with the RPM install of PHP. Since this was built from the .src.rpm of the same version should it update the existing PHP? What do I need to do/worry about here? 

Background:
I have php-4.2.2-17.2.i386.rpm installed
I just installed php-4.2.2-17.2.src.rpm modified the php.spec (not that it matters because I modified the configure portion) and ran rpmbuild -bp php.spec. I want to run configure/make/make install on my new php-4.2.2 but am concerned about the impact on the installed RPM version.

Thanks,
Roger
