File access privilege issue

[cx2671206]

I installed thrift_client gem as a dependency of other gems, and the other gem complaint that it can't find thrift_client.

After dig into the code, it turns out that thrift_client doesn't give 'r' permission to all user. After running 'sudo chmod -R a+rX /opt/ruby-1.9.3/lib/ruby/gems/1.9.1/gems/thrift_client*', it works.
