I've been putting together a server that's completely devoid of X. I do a bit of mapping, so I need sci-geosciences/grass. To my dismay, I find that it deps on x11-terms/mlterm if have the nls USE flag, plus it deps on all sorts of x11 libs if I don't use motif. Is this not a bit overzealous? I have absolutely no X libraries or apps intalled on this machine, and I just now compiled it --nodeps and without the motif use flag, and it compiled just fine. I'm also of the opinion that if I set the nls use flag and compile it without having mlterm installed, it'll compile just fine again. I plan on doing just that tomorrow and I'll report back here once I do.
As expected, USE=nls and emerge -va --nodeps grass Just Works
As expected, USE=nls and emerge -va --nodeps grass Just Works. I can assure you I have absolutely none of the deps grass 6.0.2 claims to need installed on my system: fungus ~ # emerge -va grass These are the packages that would be merged, in order: Calculating dependencies... done!

First, it sounds like what you really want is mapserver and libgrass. Second, the current deps are a result of both the stated upstream requirements: http://grass.itc.it/grass61/source/REQUIREMENTS.html and poking at the binaries and libs with ldd to see what's actually linked in. It may be that an additional USE flag could lighten it up a bit, but there are a still several pieces of Grass linking against various X libs. Also, the list of libs above more than the deps in the Grass ebuild. If you'd like to submit a modified ebuild or patch, I'd be happy to check it out...

Grass 6.1.0 is in the tree with updated flags and such; the X deps are a function of several USE flags and their dependencies. Try compiling with USE="-X -glw -opengl -tcl -tk".
