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...).

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
