Wrapping a plug-in for multiple computers?

[FullCode]

I'm developing a VST plug-in and I'd like some people with Pro Tools to give it a try so I used the VST to RTAS wrapper create a quick and dirty RTAS version. But when I transfer the wrapped files to another computer the plug-in does not work at all. You can instantiate it, but the GUI is totally gone.

I put the wrapped DPM file in the Pro Tools plug-in folder and I put the corresponding VST plug-in in the "Macintosh HD/Library/Audio/Plug-Ins/VST", which is the same spot on the computer that did the wrapping. It seems like with the same paths and files on both computers that it should work, but clearly there is something I'm missing.

Any help is greatly appreciated.
