Were it I (and I know it ain't; YMMV, etc), if would second ike's recommendation with these mods:

"...and ask him/her if (s/)he has any problems with you using Perl (and the CPAN modules mentioned above) for this assignment."

Yes, first is a nitpicking joke, but, mindful of the "little tin god" warning above, the second may be important.

good luck!
