Re: [Sbcl-help] gmp and mpfr support - how to install?

[Stephan F. <def...@go...>]

Hi,

I had some private mail exchange with Harmut and according to him SB-GMP 
(and MPFR) works on Gentoo (amd64) with GMP 6.0.0a and SBCL 1.2.8.

I am having the below problems with SBCL 1.2.4 and 1.2.8 on Kubuntu 
(amd64) and the same GMP 6.0.0a. Clearly something strange is going on. 
Anybody else having similar non-working behaviour?

Regs,
Stephan
