Yes, indeedie.  So the necessary cmake command line for FreeBSD 5.5 was:

cmake -DGRASS_PREFIX=/usr/local/grass-6.3.cvs
-DQT_QMAKE_EXECUTABLE=/usr/local/Trolltech/Qt-4.2.2/bin/qmake
-DCMAKE_SHARED_LINKER_FLAGS=-pthread
-DCMAKE_MODULE_LINKER_FLAGS=-pthread -DCMAKE_EXE_LINKER_FLAGS=-pthread
.

This got everything to compile and link.  I haven't tested whether it
runs properly yet, because I'm not near the machine and can't run it
remotely over dial-up.  I'll report later if there's any problem
running it.

I don't have any machines currently running FreeBSD6, so can't check it there.
