best method to recompile php for fc3

[Dale Sykora <dalen@xxxxxxxxxx>]

I recently had to recompile php on FC3 to accomodate oracle instant 
client libraries.  I downloaded the source from php.net, configured it 
with the same options as shown by phpinfo() from the original FC# php 
package.  I then added the oracle option.  I ended up removing a few 
options (imap, etc) so it would work without error.  I would rather have 
 installed the php srpm and recompile from that so that the end result 
is very close to the original rpm.  However, I do not know the steps 
involved and had trouble googling for them.  Does anyone have 
instructions or a howto for making minor changes to files from a source 
rpm and recreating a new rpm.

Thanks,

Dale
