gaim-evolution is going to be pretty very big than gaim, so yes it's best  
to create dozen slave ports.

Can add more knobs like my example above, but the 'HAVE_GNOME:Mfoobar' is  
a good feature that you can use WITH_GNOME define to enable this. So, you  
can put WITH_GNOME=yes in /etc/make.conf, then all your ports will that  
has autocheck of GNOME stuff will be enable by default.

Contract to the maintainer and request for add PACKAGE_BUILDING to have  
the good default in package. If they disagree, then create a slave port.  
My port, in fluxbox-devel and wesnoth have the good default for package,  
so it's depending on how maintainers deal with the ports.

When port has the option that will getting a huge dependencies like  
gaim-evolution, then it's best to create a slave port for package.
