While the code and documentation is subject to copyright, and while the Perl logo is a registered trademark, neither prevent the implementation of a Perl parser or compiler. As such, no license is needed.

I can't find any protection for the name "Perl", so you could even use Perl in your product name. It would be more polite to go the "Foo: A Perl Compiler" route, though.

Since you asked about licences, there are three publicly available.

Perl is distributed using two licenses: the Perl Artistic License and the GNU General Public License. Again, neither are relevant, since you're not asking to distribute Perl's code and documentation.

The terms for use of the trademarked logo are found here, although there is a blatant lie on that page. ("Anyone who uses any Perl mark is required to comply with these use guidelines")
