Gnome 2.9 vs net/gaim

[Ade Lovett]

net/gaim does not package correctly when built against gnome 2.9, due to 
evolution-data-server pkgfiles now being libebook-1.2/libedata-book-1.2, 
changed from the 1.0 files that the configure script is looking for.

Either unconditionally disable evolution support for now, or apply the 
patch at http://people.FreeBSD.org/~ade/patch.net.gaim to fix this issue.

Whichever way is chosen, looks like net/gaim needs to be brought back 
into the development repository for now, given the incompatibilities.
