I only use -stable, I am trying to build mozilla-firefox on 5.3-stable
GENERIC.MP.
It is on a laptop's local hard drive, not external. I did "rm -Pr
/usr/obj/ports/locks", reboot, start make of
/usr/ports/www/mozilla-firefox and it's still awaiting lock.
In /etc/mk.conf I've had it for a few stable releases
USE_SYSTRACE=Yes
SUDO=/usr/bin/sudo
WRKOBJDIR=/usr/obj/ports
DISTDIR=/usr/distfiles
PACKAGE_REPOSITORY=/usr/packages
PIPE=-pipe
MOTIF=lesstif
CLEANDEPENDS=yes
REFETCH=true
FORCE_UPDATE=Yes
BSDOBJDIR=/usr/obj
BSDSRCDIR=/usr/src
XSRCDIR=/usr/xenocara
XENOCARA_BUILD_DRI=yes
I have not tried building any other ports if mozilla-firefox doesn't work
