Porting a small open-source C# code that uses Ghostscript to MAC

We have a few hundred lines of open-source C# code that take PDF files, convert them to images using GhostScript, and then do some simple processing to fix up the image and format it in a format which is used by other applications. We want to port this code and package it to be able to run on Mac OS. The users should be able to download the package and install it on a Mac directly without having to download anything else. The final code you produce will also be open-source. Most of the c# code files can be downloaded from here: [login to view URL]
