panda: get a functional installation

[mojca (Mojca Miklavec)]

Now that rakudo is available, it would be nice to get panda working.

Most likely we will have to work with upstream developers to get the installer behave in the desired way. For example, the build ends up with

==> Please make sure that inst#/opt/local/var/macports/build/_path_to_perl_lang_panda/panda/work/.home/.perl6/2015.12/bin is in your PATH

According to ​http://www.in-ulm.de/~mascheck/various/shebang/#interpreter-script we have to fix the shebang call to perl6. Having

#!/opt/local/bin/perl6

doesn't work.

One of the errors:

Found no writable directory into which panda could be installed
  in sub make-default-ecosystem at /opt/local/share/perl6/sources/310EA749D1E286A42C504F792C75260CCFC8D622 line 19

See:

• ​https://github.com/tadzik/panda/pull/264/files

The problem is in this line:

try mkpath $pandadir unless $pandadir ~~ :d;

in lib/Panda/App.p.

I committed r144009, even though I'm not 100% satisfied with it yet.

But you can now run

panda install Task::Star

which will put files under $HOME/.perl6/2015.12/panda.

It now fails while building Linenoise:

==> Fetching Linenoise
==> Building Linenoise
===SORRY!===
P6M Merging GLOBAL symbols failed: duplicate definition of symbol Panda

Next time try to use

RAKUDO_MODULE_DEBUG=1

to get more debug output.

And on ​10.6 it fails with:

Will, I need some further help with Panda. See the following:

$ panda install Readline

All tests successful.

This is an absolutely undesired behaviour of Panda. All the files should go to $HOME/.perl6/2016.01 instead of the random directory that was initially used to build rakudo and has already disappeared by the time I ran panda.

Later on I get a lot of other problems:

These are the files that come with readline:

  /opt/local/lib/libreadline.6.2.dylib
  /opt/local/lib/libreadline.6.3.dylib
  /opt/local/lib/libreadline.6.dylib
  /opt/local/lib/libreadline.a
  /opt/local/lib/libreadline.dylib

No *.so files are present.

In 692e5c4297e786565c72f22672b4b44a255f97fc/macports-ports (master):

panda: delete port

The upstream development has been abandoned, calling zef a replacement.
It also no longer works with recent versions of rakudo.
