You can't growfs(8) a filesystem unless there's spare space in the
partition. To increase the size of the partition on a plain disk
drive usually requires a lot of fiddling about with disklabel(8) and
probably backup and restore of large chunks of the disk.

OK. Two work-arounds.
i) Find a partition with plenty of spare space (use df(1)). Lets
assume that partition is mounted at /foo. Now create /foo/tmp
and change the permissions etc. so it can be used as a temporary
directory:
# mkdir /foo/tmp
# chown root:wheel /foo/tmp
# chmod 1777 /foo/tmp
Now set the TMPDIR environment variable to point to /foo/tmp:
# setenv TMPDIR /foo/tmp (tcsh, csh etc.)
-or-
# TMPDIR=/tmp/foo ; export TMPDIR (sh, bash etc.)
and try doing your install again. Chances are it will honour the
TMPDIR variable. If it doesn't, move aside your existing /tmp
directory and create a symlink to the new one:
# cd /
# mv tmp tmp.old
ln -s foo/tmp tmp
You should delete the link and move the old /tmp directory back
into place when you're done, as a number of programs tend to keep
unix domain sockets under /tmp, and various things will
mysteriously not work properly until you do. Either that, or
reboot.
ii) If you have plenty of swap space mount a mfs on /tmp:
# mount_mfs -o rw /dev/ad0s1b /tmp
Same caveats about unmounting after use
Cheers,
Matthew
