Installing Sproutcore on Ubuntu 7.04

I know, I know, 7.04 is old now, but I still haven’t upgraded my laptop.

I tried the standard

$ sudo gem install sproutcore

but I had issues with nokogiri:

Install required dependency nokogiri? [Yn] Y

Building native extensions. This could take a while...

ERROR: While executing gem ... (Gem::Installer::ExtensionBuildError)

ERROR: Failed to build gem native extension.

Don't know how to build task 'extension'

I found some references to using `upgrade –system’ to upgrade the gem software components, but this didn’t work for me. Instead the following worked:

$ sudo gem update --system

This upgraded my gem installation, but it still needed this patch in order to run.

After all this the Sproutcore installation went smoothly.
