Howdy, Can you verify that the problem still occurs with the latest Math::BigInt, 1.89 ? Also, the output of the following commands would be useful: perl -V gcc --version (or which ever compiler you are using) uname -a Cheers, Duke On Thu, Nov 19, 2009 at 3:56 AM, kishore reddy via RT <bug-Math-BigInt@rt.cpan.org> wrote: Show quoted text

This is not a bug. The source lies in Crypt::DH, as indicated by the error message: Show quoted text
> Math::BigInt: couldn't load specified math lib(s), fallback to > Math::BigInt::Calc at /usr/lib/perl5/site_perl/5.8.8/Crypt/DH.pm
Crypt/DH.pm contains the line use Math::BigInt lib => "GMP,Pari"; which causes Math::BigInt to look for Math::BigInt::GMP. If it can't find it, it looks for Math::BigInt::Pari. If it can't find that either it will fall back to Math::BigInt::Calc. To get rid of the warning, install Math::BigInt::GMP or Math::BigInt::Pari.
