Installation Issue

[Matt Woodward]

Hi there--I'll start by stating that I have zero experience with Ruby
(mostly a Java guy), so I apologize in advance if my issue is related
to basic Ruby noobness.

I'm trying to install OCW on Linux 10.04 and I get as far as step 7,
at which point I see the console output below.

Any assistance is greatly appreciated, and I'm happy to provide any
details on my environment that may be necessary. Thanks!

Matt,

It's trying to compile a gem that uses C extensions and failing. You'll
need to install a C compiler and the Ruby headers. On Ubuntu, you'll
need to run a command similar to this to install them:

sudo apt-get install ruby1.8-dev build-essential gcc autoconf libtool

Perfect--thanks! Got past this and resolved all the other dependency issues I ran into, and the app is up and running. Really appreciate the help!
