When I tried to install x11/kde4-workspace I get this:
I didn't find anything on this and I don't know how to build it 
ps: I'm new to FreeBSD
Code:
......
===> kde4-workspace-4.8.4 depends on shared library: gps.20 -not found
===> Verifying install for gps.20 in /usr/ports/astro/gpsd
===> Returning to build of kde4-workspace-4.8.4
Error: shared library gps.20 does not exist
***Error code 1***
stop in /usr/ports/x11/kde4-workspace
