Installation Errors

[ClickerMonkey]

Heres some errors we were getting after we did 'sudo apt-get install
rubygems gem' on our ubuntu hard system.

Building native extensions. This could take a while...
ERROR: While executing gem ... (Gem::Installer::ExtensionBuildError)
ERROR: Failed to build gem native extension.

ruby extconf.rb install god
extconf.rb:1:in `require': no such file to load -- mkmf (LoadError)
from extconf.rb:1

Gem files will remain installed in /var/lib/gems/1.8/gems/god-0.7.8
for inspection.
Results logged to /var/lib/gems/1.8/gems/god-0.7.8/ext/god/
gem_make.out

And ofcourse gem_make.out only says the above error, useless!

I don't know a single thing about gem or ruby, we just want god
because monit isn't working out for us!

You need to install the ruby development libraries too (this is needed
for any gem with C extensions)

sudo apt-get install ruby1.8-dev

You maybe also need the hardy development deb

sudo apt-get install build-essential
