How to enable "--with-pdo-sqlite" in PHP

[rainer]

I want to run ClearBudget on a Virtual Gentoo Server. For this, I need PHP recompiled with "--with-pdo-sqlite".
Is there an easy way to do this (USE flag or so)? "sqlite" is enabled already.
Thanks,
Rainer

I suggest you edit the ebuild directly and add it. Then:

ebuild /path/to/php/ebuild.ebuild digest

And then you can recompile .
