I will edu-guess it's the old "library-version-binary-mismatch"No - the message is merely a response to an attempt to use (I think) Math::BigInt::GMP or (if that fails) Math::BigInt::Pari or (if that fails) Math::BigInt::BitVector. When those libs are unavailable, you get the messages that the OP quoted, and the pure-perl (slow) Math::BigInt is used instead. Nothing there that's going to cause any problems (except for speed of processing).
I don't know if anyone here is interested in helping with Net::SSH::W32Perl - I know I'm definitely *not*. I have had some success on Windows with Net::SSH2 (available as a ppm from the uwinnipeg repository). Unfortunately, it too is less than ideal as there are some bugs with it on Windows - though I've so far managed to find workarounds for those bugs (in so far as they affect me). If
cristianekw likes to give it a go, and has trouble, I'll try to help out.
Cheers,
Rob
