Difficulty Installing Module on Latest Rakudo Star

[Joe Polanik -X (jpolanik - RESOLVIT RESOURCES LLC at Cisco)]

I'm trying to install Bailador on a Mac running OSX 10.11.4 with the Latest 
Rakudo Star (2016.04). The installation fails on a dependency.

Digest::HMAC can't be installed using

sudo panda --prefix=/Applications/Rakudo/share/perl6/site/bin/ --force install 
Digest::HMAC

The error message says


Could not find Digest at line 6 in:

    /Applications/Rakudo/share/perl6/site

    /Applications/Rakudo/share/perl6/vendor

    /Applications/Rakudo/share/perl6

However, Digest itself is installed. It's visible in the file system browser 
and my .per.6/panda/state file lists it as having been successfully installed.

Any advice would be appreciated.

Thanks,

Joe
