That's a nice little demo of how to set up a simple perl extension - though there are already a number of modules in existence that will do the conversion.

<plug>
Math::GMPz already uses the very same gmp library function: 
perl -MMath::GMPz=":mpz" -wle "print Rmpz_get_str(Math::GMPz->new(54),
+ 13)"

[download]
</plug>

It's also available with Math::GMP, too (though the Math::GMP function we use is undocumented): 
perl -MMath::GMP=":constant" -wle "print Math::GMP::get_str_gmp(54, 13
+)"

[download]
There are other modules, too, that one could use, but these are the only modules I know of that use the gmp library for the task.

Cheers,
Rob
