Upgrading gdlib for PHP 4.2.2 on RH Linux 9

[rogair]

I have PHP 4.2.2 installed with gdlib support (gdlib 1.8.4 that comes bundled). New code requires gdlib 2. I tried installing gdlib 2.0.33. configure, make, make install all ran without error. I ran ./configure --prefix=/usr as is instructed for upgrades. I've restarted everything, but PHP still seems to think I do not have GD 2 installed. Do I have to rebuild PHP?!? Anyone encounter this before, or have any thoughts?

You have to recompile php using --with-gd=[path/to/gd/libs] in the configure command. Unpack the source tarball, go into the directory and run ./configure --help | less for more info.

PHP was already configured with gdlib. I am simply updating gdlib. PHP already has the path to gdlib as it hasn't changed.

Unfortunately this box has PHP 4.2.2 installed from RPMs and not from source so I want to avoid mucking with it.
