Thanks! That's super helpful.

I tried just putting "system" before the command but it didn't work.
I couldn't find the documentation for tcl's system, so I tried using
destroot.cmd "${prefix}/bin/rakudo" ... instead, but it added extra
arguments: install DESTROOT=... which break the command. But erasing
destroot's args, pre_args, and post_args fixed the build.

Then the problem was activating it. It said:

  Error: Failed to activate raku-zef: Image error:
  /opt/local/share/perl6/site/version is being used by the active rakudo port.
  Please deactivate this port first, or use 'port -f activate raku-zef' to
  force the activation.

So I added the removal of that file to post-destroot and now it works!
It installs and avtivates...

However, when I now test with "sudo port install -vst raku-zef", and add the
missing dependencies (curl, git, wget), I get this error:

  :info:destroot Failed to create directory '/opt/local/share/perl6/site/short' with mode '0o777': Failed to mkdir: Operation not permitted
  :info:destroot Command failed:  cd "/opt/local/var/macports/build/_Users_raf_macports_ports_lang_raku-zef/raku-zef/work/zef-0.21.1" && /opt/local/bin/rakudo -I"/opt/local/var/macports/build/_Users_raf_macports_ports_lang_raku-zef/raku-zef/work/zef-0.21.1" bin/zef --to="inst#/opt/local/var/macports/build/_Users_raf_macports_ports_lang_raku-zef/raku-zef/work/destroot/opt/local/share/perl6/site" install /opt/local/var/macports/build/_Users_raf_macports_ports_lang_raku-zef/raku-zef/work/zef-0.21.1 
  :info:destroot Exit code: 1

And now, I get the same error without -vst. Wierd, that did work before trying -vst.
And port test isn't working anymore either with teh same error.

  $ ls -lasp /opt/local/share/perl6/site
  0 drwxr-xr-x  3 root  wheel   96 26 Nov 11:58 ./
  0 drwxr-xr-x  7 root  admin  224 26 Nov 11:58 ../
  0 -rw-r--r--  1 root  wheel  1 26 Nov 11:57 version

Any idea what's happening? Or what to try next?

I tried uninstalling and reinstalling rakudo just in case it might
help, but it didn't. My current attempt is
