Hylafax ebuild (at least for > 4.1.8) depends and builds xorg-x11, even when the -X USE flag is set. This is probably not necessary, since hylafax itself has no need for X.
Post 'emerge --info' and 'equery g hylafax' output and reopen then.

As you can see, it's actually app-text/ghostscript that pulls in X; cups with USE=motif is known to pull in X11 as well (via xpdf). Additionally, I see you have gtk gtk2 set. You'll have to clean up your use flags a bit more if you don't want X; USE="-X" emerge hylafax won't do the trick.
