[BUG] Bus Error / [BUG] Segmentation fault

There seem to be many bug reports here about using the rubystack with osx snow leopard. My bitnami redmine system works fine, but ruby crashes when sending email. Running the redmine test suite shows that the problem is the binaries:
alpha:redmine redmine$ rake test:coverage(in /Applications/redmine-0.9.3-0/apps/redmine)
rm -f coverage
rm -f coverage.data
Loaded suite /Applications/redmine-0.9.3-0/ruby/bin/rcov

Maybe the problem is the non-existing libruby.dylib?

alpha:redmine redmine$ otool -L /Applications/redmine-0.9.3-0/ruby/bin/.ruby.bin

I’ve read in the forum that you’re about to release a new stack which fixes those problems.

Right, we just released a new RubyStack version (2.1-0) which fixes this issue. Enjoy!

Yes, it fixed my problem with email (and hopefully subversion).
Thanks Beltran!
