Compiling HandBrake 1.3.3 using Alien Bob's Script Error.

So I am using Eric's 1.3.2 HandBrake and I am perfectly happy with it, however about 6 weeks ago I installed current in a VM and was able to compile 1.3.3 HandBrake with his SlackBuild. However on the newest current installed in a VM today I am getting an error. This is no big deal, but I thought I would paste it here to see if anyone has had the same error or can see a possible fix. Again 1.3.2 is working fine so this is not a big deal. I think I got the most relevant part of the build info here...
