using vim as an example, currently the port recognises env variables 
like most other ports do. e.g. WITH_GTK2, WITH_ATHENA etc.. these 
generally make changes to the CONFIGURE_ARGS.  Regarding package 
building, there is an option (with the vim port) for PACKAGE_BUILDING 
which builds with the most common options. I'm not exactly sure what 
kind of answer you were looking for, but just my little input on the 
subject :)
