It very well may be.

DISCLAIMER: I've never used a Mac with Linux before, so anything I say
here should be looked at VERY carefully.

Ok, try "swapon -a" (should start swap).  Watch carefully to see if it
complains about any missing devices.  If it does NOT complain, try
"swapon -s" and see if it's working.

If "swapon -a" DOES complain, you may need to change your /etc/fstab
to use the "/dev/sda4" nomenclature rather than "LABEL=swap-sda4".  It
may be that swapon doesn't recognize the label on the filesystem.  You
can also try "swapon -L swap-sda4" (to manually try to force the label) 
or "swapon /dev/sda4" (to manually use /dev/sda4).
