could you debug this error ? Thanks!

1>software version: Net-SSH-Perl-1.34 http://search.cpan.org/%7Eturnstep/Net-SSH-Perl-1.34/ perl 5.8.6

2>run source code in solaris:

#!/tools/openbin/perl/5.8.6/sparc-sun-solaris8/bin/perl -w
#use strict;
use Net::SSH::Perl;
use Net::SSH::Perl::Constants qw( :msg );
my $ssh = Net::SSH::Perl->new("10.10.6.159", debug => 1,protocol =>2);

# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,

By the way, I had this same problem and installing

Math::BigInt::GMP

Corrected it.
