Building PHP modules makes it very easy to load optional functionality
however it will decrease performance, sometimes drastically.
I hand build PHP because of this reason and also because I want upgrades
as soon as they are released and ports usually lags a few days.
It is also possible something changed in PHP between the two installs,
I'd try a hand compile of PHP without using modules for the
functionality you know you want.
There is a lot of really good information available about tuning PHP +
Apache that can be accessed by searching on google.com.
