This is an earlier version, but '0.16' causes problems
not only in your system.
Comment : Debian has its own names for CPAN perl modules,
some names are rather different from the original, and not
always logical.
If you still have problems : The 'perl' you have in
/usr/local/lib seems very different from the default
Etch version in /usr/lib/perl/5.8.8/ , so an alternativ
solution is simply to use the default one.
