Speaking of which, I've just closed Bug #324665 (Merge dev-php5 and dev-php) as RESOLVED FIXED. After a year of procrastination, I've finally whipped up a script to migrate the complete
dev-php. Thanks goes to olemarkus and darkside for checking my script and suggesting ways to go about this.
If there are any issues with the migration, please comment here or on the bug.
P.S.: Yes, I know the overlay is broken because of this. Neither Ole nor me have any use for it at the moment. Plus, merging user-contributed stuff (thanks jamie!) from the overlay to the gentoo-x86 cvs tree is just plain painful. So unless we can keep Gentoo PHP development completely in the overlay and make the push as simple as
git pull overlay, you probably won't see much action in the overlay.
