After installing Rakudo star into some other directory using --prefix I tried to run panda and got the following error:
-------- Found no writable directory into which panda could be installed in sub make-default-ecosystem at /home/travis/rakudo-2014-12-1/languages/perl6/lib/Panda/App.pm:18 in block <unit> at ./rakudo-2014-12-1/bin/panda:11 -------- It worked when I installed Rakudo Star after building it without any --prefix. Is this an integration bug between panda and Rakudo Star? Can I solve this somehow? Gabor
