The best solution is to create a slave port, gaim-evolution or
gaim-whatever.

This is correct way. If you want it to be add in the package, then just
add defined(PACKAGE_BUILDING) like this:
.if ${HAVE_GNOME:Mevolutiondataserver}!="" || defined(PACKAGE_BUILDING)
But, I don't think it's good idea and best to do is create a slave port
because not everybody want this feature.
