How to configure PHP build?

[Gabriel Ambuehl]

Hi,
after the last PHP commits, I can't seem to be able to configure my
PHP builds anymore. It keeps on telling me
===>  Found saved configuration for mod_php4-4.3.8_1,1
and subsequently starts to build right away.

Is there any way to get it to behave like in the past, specifically
asking me what libs it should compile in?

Any help would be greatly appreciated.

Regards,
Gabriel
