Really fix the CDROM install of Staroffice. CD_MOUNTPT was defined to late in
bsd.port.mk. This caused the staroffice installation to fail. Also do not download
the distfiles if we do a CDROm install.
Since I have got now a "old" SO-cdrom, I could test the install and it works now.
Over to portmgr to handle the bsd.port.mk changes
Patch committed, thanks
