I stand corrected. After I posted that above message I got to thinking about my host and the extensions I've installed in the passed. I contacted my host to confirm that I indeed was running php5 as stated in the server control panel. Well, turns out no. Those genius's have php4 and php5 installed, but by default php4 is set to be used. So I had to go into my local htaccess file and add a line of code to switch my host account to use the actual php5 version that I posted previouly.
My appologies, your plug installs fine after I made that correction.
