  • The error message `You have to install development tools first.` means that a compiler wasn't found in your path. You likely need to install either XCode Command Line Tools or gcc. The `gem_make.out` log referenced at the end of the error should have more details. The solution should be similar to [this question on StackOverflow](http://stackoverflow.com/questions/10344821/gem-install-pg-doesnt-work-on-osx-lion). – Stennie Dec 02 '13 at 00:50

try

gem update --system
gem install bson_ext

if all else fails download the gem http://rubygems.org/gems/bson_ext and add it to your gemsets manually

I had the exact same issue and installed gcc to resolve, thanks for the hint by gspatel.

yum install gcc
