Fixed this issue: Building native extensions. This could take a while…

I got this error when i tried to install various ruby gems on system.

I am using the Fedoa 9 as OS.  I tried a lot to fix this issue and googled lot but not found exactly solution.

later on realize some of latest software are not installed on OS that’s why i am getting these kind of error.

you need to install proper software on Fedora box.

# yum install ruby ruby-libs ruby-mode ruby-rdoc ruby-irb ruby-ri ruby-docs

#yum install gcc-c++

this is the solution.
