This is a CPAN question.
But yes, the Distroprefs mechanism is perfectly suited to supply
additional parameters to one of the installation commands on
a distro by distro basis.
You would have to place a YAML file (or Data::Dumper output
file) in your preferences directory ("o conf prefs_dir" in a
cpan shell queries/sets the location), where you set a value for
"commandline" in the "pl" stage. Examples can be found in the
distroprefs subdirectory of the CPAN distro.
Have fun!
