Actually I've removed the patches and written a thin wrapper class instead 
in boost/math/bindings/rr.hpp.  Hopefully folks will provide bindings for 
other popular packages at some point as well :-)

Only trouble you might have:

* NTL's error handler aborts on error: including on numeric *underflow*, 
something I find really annoying :-(
* NTL's << streaming operator is temperamental: has a habbit of writing out 
the result as an integer where possible, even if the number of digits far 
exceeds what you can paste into C++ code as a literal.  There's no way to 
force it into scientific mode either.

Other than that it would be interesting to hear your experiences of using 
this.

HTH, John.
