Math::GMP and Pari Installed, But BigInt Can't Find Them

[MaggotChild]

perl -MMath:ari -e'$a=PARI 2;print $a**10000'
#Big number...

perl -MMath::GMP -e'print Math::GMP->new(2) ** 1000'

#Same Big Number...

perl -e'use Math::BigInt lib => "GMP,Pari";'

Math::BigInt: couldn't load specified math lib(s), fallback to
Math::BigInt::Calc at -e line 1

What gives?

As an aside, is it possible to import GMP or Pari from the command
line? -M doesn't play nice with a string of import args:

perl -MMath::BigInt='lib,Pari' -e'1'

#OK, can't load module error

But:

perl -MMath::BigInt='lib,"GMP,Pari"' -e'1'

"Pari"" is not exported by the Math::BigInt module
Can't continue after import errors at -e line 0
BEGIN failed--compilation aborted.

You also need to install Math::BigInt::GMP and Math::BigInt:ari. (I
believe the former doesn't actually use the Math::GMP bindings at all,
and instead links with the C library directly.)

Doh! OK, thanks.
