MPL is not adapted from GPL.

AOL has had nothing to do with Mozilla since July 2003.

I said you can't relicense copyrighted material without permission of 
the copyright holders.

You posted asking "Which licence do I have to choose for my software? 
GPL, MPL, ...?".  I replied that you can't relicense without permission 
from copyright holders.  If you don't know what copyright is, ask a 
lawyer.  If you preserve the license on the Rhino code you ported to C#, 
that is not relicensing, and it does not require permission of copyright 
holders, but your new work is bound by the terms of those licenses.
