Unfortunately, the build of perl6-zef with cowbuilder is already broken with cowbuilder. The nonexistant home dir leads to build failures.

I get a lot of warnings like:

WARNING: unhandled Failure detected in DESTROY. If you meant to ignore it, you can mark it as handled by calling .Bool, .so, .not, or .defined methods. The Failure was:
Failed to create directory '/nonexistent/.raku/short' with mode '0o777': Failed to mkdir: No such file or directory
  in sub MAIN at /usr/bin/prove6 line 3
  in block <unit> at /usr/bin/prove6 line 1

And the build fails with:

===SORRY!=== Error while compiling /usr/lib/perl6/vendor/sources/B4401FC2C8E71132AE0D3CE2C47A7D2FBB0D50F1

All the best
