Well, they are most of the time. Unfortunately, that's not enough. That's why nqp
and rakudo packages are now arch dependant.

The main problem with shipping precompiled binaries is that, all of them must
be recompiled whenever rakudo is upgraded (or downgraded). This would require
to setup automation on Debian build server to recompile all Perl6 modules every
time rakudo is updated. 
This requires to ship Perl6 source with the package otherwise, we'll have to re-upload
all modules for each rakudo release. This won't scale well.
The messages  mentions another alternatives:
- run pre-compilation at package installation
And there's also another possibility:
- ship only sources and let rakudo compile module when needed
The latter option is the simplest for us, but it will somewhat fill up user's ~/.perl6 directory.
All in all, the latter option is still better than doing nothing. I guess we will be able
to improve the packaging when we better understand rakudo's compilation mechanism.

you mean perl5's pod2man ? if yes, Perl6 pod is different from Perl5 pod and
can't be parsed correctly by perl5's pod2man.

Unfortunately, the compatibility of pre-compiled file is broken any time rakudo is updated.
There's a very strong coupling between the version of moar, nqp, rakudo and pre-compiled files.
Let's cross this bridge if we need to ship pre-compiled files.

I'll have a look.
Many thanks for your work :-)
All the best
