You can fix the missing perl dependencies by installing them one by one or by simply using make fixdeps command. In order to use the make fixdeps command for fixing the missing packages, configure CPAN shell and install cpanminus.
{{{
# perl -MCPAN -e shell
}}}

{{{
CPAN.pm requires configuration, but most of it can be done automatically.
If you answer 'no' below, you will enter an interactive dialog for each
configuration option instead.

Would you like to configure as much as possible automatically? [yes] yes

Autoconfiguration complete.
