Title: Please merge to fixup ruby build environment on quantal.

Ruby 1.9.x is the default and when installing ruby1.8-dev, one gets the error:

/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in 'require': cannot load such file -- mkmf (LoadError)
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in 'require'
from extconf.rb:1:in '

'
rake aborted!

So the ruby1.8-dev files are not picked up and useless for our case.
