[SOLVED]White screen instead of login page? Problem with making database connection?

[pgentoo]

Problem Solved. It turns out PHP on gentoo defaults to having PDO support turned off. Maybe there was a switch to PDO as part of vacancy's UI updates? Anyway, it works now! I had to add quite a few use flags in when compared to the ones listed in the current Gentoo installation wiki.

I'll update the gentoo instructions to support current RC6/SVN code base, but only after I do another clean install to ensure I didn't forget to document something.
