During testing I didn't thoroughly checked that env var there. I suppose, it could be deleted or set to nil and left to the user to set it himself. As I said, I wrote the port for me, and uploaded it for others to test, as I couldn't figure out a (better) way to set it in the startup item and didn't find documentation on how macports would handle this case.
