Symbol not found error

[DIGITALSQUAD]

I've installed by ruby, but I've got an error below.

LoadError (dlopen(/Users/Macmini/Projects/Pubdictionaries/pubdictionaries/PubDictionaries/lib/simstring/swig/ruby/simstring.bundle, 9): Symbol not found: __ZTIN10__cxxabiv115__forced_unwindE
Referenced from: /Users/Macmini/Projects/Pubdictionaries/pubdictionaries/PubDictionaries/lib/simstring/swig/ruby/simstring.bundle

Any ideas?

This error seems to be caused by ruby version.
Now works fine with ruby-2.0.0.
I would appreciate if you list ruby versions which supported.
