NYCPHP Meetup

I have both 4 and 5 installed on a few boxes. Switching between them
is a matter of changing which libphp is commented-out in httpd.conf,
and restarting apache.

The only place where you have to be careful is with the CLI php -- it
will get overwritten on make install. Causes trouble if you have
command line scripts that care which version you are using.

You can always compile php4 --disable-cli to eliminate the problem.
