. Both are GPL.
We cannot link pure GPLed library to Ruby for licensing issue. Last
time I checked none of these multi precision numeric libraries
satisfied our criteria (license, portability, etc). GMP (or CLN or
whatever) can be used via extension, and we are happy to offer help if
required.

I just checked ... GMP is LGPL. Would that work?
