Err...  Digging further, I found out that RIPEM included RSAREF, and
it was RSAREF itself that had been modified in such a way that it
became a derived work of GPLed work.  So this modified version of
RSAREF could only be distributed under the GPL, which neither the
patent license nor the copyright license under which RSAREF were
provided permitted.

So is looks like it is the main program (SSH?) that was the
distraction.  Anyhow, if you have pointers to more specific
information about what the FSF actually wrote (all I found was
second-hand hearsay), I'd love to know more about it.
