apache-2.2.16 hit the main tree two weeks ago but is not in the prefix tree. The following two ebuilds are basically ecopies of the necessary ebuilds with proper prefixed paths where applicable. They're marked as ~x64-macos but work on ~x86-macos as well. Patch files contain no changes to the existing ones from older ebuild versions and are included for the sake of completeness.

I synced both packages, looks like that it everything that was needed. Reopen if it isn't :)
