you may symlink it to /usr/bin if you'd like. 'sudo make install' will install to /usr/local/share/"

Laughing at my self on the post above. This script works like a charm on a virgin install of 10.7 Lion. Shout out to my Code-brother, you know who you are.

Spit out Error 1 and Error 2 towards the end but seemed to work overall...
