If you're running under FreeBSD < 7 (I think), change:
} elsif ($os =~ /BSD/) {^M
$physical_memory = `sysctl -n hw.realmem`;^M
$swap_memory = `swapinfo | grep '^/' | awk '{ s+= \$2 }
END { print s }'`;^M
to
} elsif ($os =~ /BSD/) {^M
$physical_memory = `sysctl -n hw.physmem`;^M
$swap_memory = `swapinfo | grep '^/' | awk '{ s+= \$2 }
END { print s }'`;^M
