[Ssh-sftp-perl-users] Net::SSH::Perl --Unequal Access

[Pierce, S. <Sea...@ar...>]

Odd one here.
For a shared Perl tool some users can execute while others cannot. The error is in finding Net_SSH_PERL modules. Users have the same environment, permissions perl version and modules.  This system is unusual in that users share SSH keys to provide uniform access to a large range of test systems.
Here's the error:
Key class 'Net::SSH::Perl::Key::RSA' is unsupported: Base class package "Class::Loader" is empty.
    (Perhaps you need to 'use' the module which defines that package first,
    or make that module available in @INC (@INC contains: /export/builds/saa_sqa/tools/scaler/../../lib /opt/csw/lib/perl/site_perl /opt/csw/share/perl/site_perl /opt/csw/lib/perl/csw /opt/csw/share/perl/csw /opt/csw/lib/perl/5.10.1 /opt/csw/share/perl/5.10.1 .).

So, there is unequal access to the modules on our infrastructure system.  Modules are found and loaded for some users but not others.?!?

I found reference to a similar problem here: http://stackoverflow.com/questions/443493/what-can-make-classloader-fail-where-use-and-new-do-not.   I lack the skills to immediately digest the information and don't have a test system available to debug without affecting users.

I'm not sure where to begin to debug this one.   Any ideas would be gratefully accepted.

Thanks
