Permission denied when building native extensions with ruby 2.1.0

[ghost]

It seems like there is a problem with the permissions inside the extensions directory when installing a gem which builds a native extension. This does not happen with 2.0.0-p451.

platform: ubuntu 13.10

~$ rbenv -v
rbenv 0.4.0-89-g14bc162

~$ gem install bson_ext

Has this issue been resolved because I'm seeing similar issues when I attempt to install nokogiri using bundler? BTW, I provisioned the server using root user and deployed with Capistrano 3.2.1 using the deploy user. At this time, the deploy user is a member of the rbenv group.

to fix the problem manually (adjusting the ruby version or replacing it with a variable) :

chmod -R g+w /opt/rbenv/versions/2.2.3
