PHP 4.3.8 upgrade missing things

[Dan Rue]

Hey all, 

Usually when I build PHP, it asks me about a couple dozen things - perl
compatible reg ex's, ftp support, etc.  When I did a portupgrade last
night it didn't ask me those things - only three things (apache 2, and
two other things).  Now, I am missing some things - at least the preg
stuff.  So how do I get that stuff back?

I'm building /usr/ports/lang/php4, and i'm on 4.3.8. 

Any hints?

tia,
