I have tried with Spearfish, GRASS 6.4.0RC4, Linux 64bit:

v.label  map=roads colum=label font=/usr/share/fonts/TTF/Vera.ttf
d.mon start=PS
d.labels labels=roads
d.mon stop=PS
kghostview map.ps

No problem, looks fine.
It seems to be Mac specific.

could fork() in
 lib/driver/main.c
be the problem?
