But on the old machine, there is one of these files:

/usr/lib/perl5/5.12.3/x86_64-linux-thread-multi/Error.pm
/usr/lib/perl5/5.12.3/Error.pm
/usr/lib/perl5/vendor_perl/5.12.3/x86_64-linux-thread-multi/Error.pm
/usr/lib/perl5/vendor_perl/5.12.3/Error.pm
/usr/lib/perl5/5.12.3/x86_64-linux-thread-multi/Error.pm
/usr/lib/perl5/5.12.3/Error.pm

[download]

And on the new machine, no such file exists:

/root/perl5/lib/perl5/5.16.3/x86_64-linux-thread-multi/Error.pm
/root/perl5/lib/perl5/5.16.3/Error.pm
/root/perl5/lib/perl5/x86_64-linux-thread-multi/Error.pm
/root/perl5/lib/perl5/Error.pm
/usr/local/lib64/perl5/Error.pm
/usr/local/share/perl5/Error.pm
/usr/lib64/perl5/vendor_perl/Error.pm
/usr/share/perl5/vendor_perl/Error.pm
/usr/lib64/perl5/Error.pm
/usr/share/perl5/Error.pm

[download]

Most likely, as I and tobyink already pointed out, Errror.pm is installed on the old machine, but is not on the new machine. Either talk to your system administrator, or the developer of the program about the prerequisites. Also consider maybe installing Error.pm via the package manager on the new machine, or instructing your system administrator to do so.

You can check on the old machine if Error is installed by using:

perl -MError -e 'print "Error.pm is installed"'
