After installing Rakudo Star on my MacOS X under /opt/rakudo, and adding
/opt/rakudo/bin to the PATH env, I get:
[ambs@rachmaninoff ~]$ perl6
src/io/api.c:306: failed assertion 'pmc'
Backtrace - Obtained 22 stack frames (max trace depth is 32).
0 libparrot.dylib 0x00e0b83d
Parrot_do_check_events + 173
things get working.
I am not aware of how this can be fixed, but I am almost sure it can (I
have a subversion installed in /opt/subversion and it did not require
such a path).
Other than this, keep the good work :)
PS: I have other "complains" but that can be discussed on later releases.
