$Net::SSH::Perl::VERSION'

I get the below segfault trying to use Net::SSH::Perl with threads. I've tried several versions of perl, Math::Pari, and pari with the same result. I found a suggestion that I should be using Net::SSH2 because Net::SSH is not thread safe. Following the Net::SSH::Perl documentation it seems I'm already using SSH-2, however, I can't get the software to run without Net::SSH installed. My first question: Is anyone using Net::SSH::Perl (and Net::SCP) with threads and, if so, how do they configure the perl installation? Thanks! Alan
