Agreed. Neill indicated that 1.5 was what he used to compile this, so we shouldn't see any 1.6 dependencies. I just suggested on a separate thread that he verify this. Please let me know if you see any issues with using 1.5.

The first wget command you pasted above downloads the executable for the MyProxy client. This is the same as what the WebStart executes.

On the <myproxy-server> value, it maybe worth displaying this on the Gateway for a user to copy/paste. It is auto-populated when WebStart works, so that information should be available.
