First of all sorry for the delay, I was in a small trip for a few days with no pc or internet connection. I added the latest version of REST Dataware to OPM(1.4.3.1). I also updated the description, author, license and version field, you should do the same in your git repository. Just open the 3 lpk files, change the fields and click the save button. Please note: usually OPM targets only stable versions, there are a few exception where the release cycle is slow. When you release a new major version, just let me know and I will update the central repository.

I only tested with carbon. Cocoa is unstable unfortunately. I also tested with qt but under windows, where qt works nicely. If I understood you correctly you cannot check a package(OPM) to install it? Try to select a package, then press space.
