in reply to Net::SSH::Perl and PARI

but I seem to have to update all modules (e.g. /usr/lib/perl5/site_perl/5.8.6/Crypt/DH.pm) to use Pari instead of GMP manually:
No you don't. All you have to do is start your program with 
use Math::BigInt qw' lib Pari ';

See MATH_LIBRARY in Math::BigInt docs.

The fact that modules like Crypt::DH and Crypt::DSA::KeyChain specify which library they prefer should have no effect on which library is actually used.

update: actually, you should use Math::BigInt qw' lib Pari '; last (after use Net::SSH...).

    Hmm, this doesn't work for me. If I manually change DH.pm to use Math::BigInt lib => "GMP"; and then make the changes to my script as per your suggestion, my execution time drastically increases (from 5 to 25 seconds) until I revert the change to DH.pm.

      I'd say its working ;)

      If you've got both Math::BigInt::GMP and Math::BigInt::Pari installed, you've effectively loaded both of them, and DH.pm is using Math::BigInt::Pari since it was loaded last :)

      See 16032 lib GMP versus lib PARI versus lib GMP,PARI.

      For now, you should only install one of them.
