Is there an equivalent env var to PERL5LIB for Perl 6 module locations?

[Tom Browder]

I would like an easy way to have a local search path for local Perl 6
modules (those not installed via Panda).

I'm used to using the environment variable PERL5LIB for Perl 5
modules.  Is there currently any equivalent way to do that for Perl 6?

Thanks.
