Still misdetected, it should be "nehalem-unknown-linux-gnu" for optimal results if you are running on an i7. But that is probably be a virtualbox issue. On the solaris side you get "i486-pc-solaris2.11", but you should be getting at least "x86_64-*" (as for linux). I think that you must fix the "config.guess" in mpir somehow... Check out http://groups.google.com/group/mpir-devel/browse_thread/thread/aeb271247ae0eec9/a90654677f9db1d5 which is quite related to this: I had the same issue running on a kvm virtual cpu, and that fixed it at least for linux. The strategy is that for 64 bit builds on x86 hardware, you always fallback to x86_64-* even if the family/model reported by cpuid seems to be of an older 32 bit only cpu. Gonzalo
