I'm not sure this is a bug report, just wanting to make sure this
problem was considered.
I remember that, when compiling GNUstep gui/xgps/apps without using the
window maker version from CVS, there is a problem with -lXmu being missing
in the linking command. I still had this problem two weeks ago when I
came back to Italy, and the fix was installing window maker from CVS (the
real fix is add -lXmu in the makefile stuff).
I'm not sure, but this could be a bug report for 0.6.6, since perhaps
people will want to use GNUstep with an older window maker/libwraster
version ?
