[Ssh-sftp-perl-users] problem using the Net SSh module

[<<<<Amar>>>> <ama...@gm...>]

hello all,
                I installed the NET::SSH::Perl module on my  SunOS 5.9
sparc (with the Sun compiler )with the command

perl -MCPAN -e 'install Net::SSH::Perl'

and it got installed "hopefully" bcos i got the message

" Net::SSH::Perl is up to date (1.30)."

but when i try to run the my script which uses this module, i get errors.

the script is as follows

use Net::SSH::Perl;
my $ssh = Net::SSH::Perl->new("veasol9-02.vxindia.veritas.com");
    $ssh->login($user, varsha);
    my($stdout, $stderr, $exit) = $ssh->cmd(ls);

and the error after running the above script is

then i try to install the Math::Pari module as follows...
perl -MCPAN -e 'install Math::Pari'

and i get the error========>

----end of error-------------

So the question is though all the dependent modules were installed(bcos i
use >> perl -MCPAN -e 'install Net::SSH::Perl')
still why it is asking me for other modules to load. N plz help me by
telling me how to load the Math::Pari module on
my SunOS 5.9  sparc.

Amar.
