using ports without X

[albi]

i wanted to try "madman" from ports on a local fileserver, but i prefer
not to compile X and Qt for this, is that possible ? 
a look at the Makefile and a google-search didn't provide any options

can someone point me to certain general "flags" for /etc/make.conf to
prevent X and Qt being build at all? tia
