installing a window manager

[Dick Hoogendijk]

Up 'till now I had a server without X. I've a need however to be able to 
graphically work on that server so I thought: I install 
x11-servers/xorg.server and after that I build windowmaker (nice and 
light). However, this does not seem to be enough to get X working.

Can somebody tell me what to build (with portmaster) to get a minimal X 
server station with windowmaker.
I run 8.1/amd64 with up2date ports.

Thanks
