I was trying to install rails on Ubuntu Natty Narwhal 11.04, using ruby1.9.1.
I installed ruby using apt-get install ruby1.9.1-full which contains the dev package. I googled the error and all have suggested I install the 1.9.1-dev which I already have.
Building native extensions. This could take a while...
ERROR: Error installing rails:
