There is:
/opt/local/etc/macports/variants.conf

where you could put:
+server

and I believe you will get the +server add to all ports that port  
builds, no?

I mentioned recently gentoo's package.mask for masking packages or  
packages above a version. Personally I'd like something like that in  
ports.

Wouldn't it be useful and simple to add the capability to /opt/local/ 
macports/variants.conf to specify a port:variant combo?
clamav+server
mysql+server

or
port:clamav +server

or
clamav mysql5 +server
guncash +nox11
