[Peter Goodall]

Public bug reported:

I installed ruby 4.5, and rubygems1.8 from the Synaptic Package Manager, and tried to do
  sudo gem install ruby-debug, and am getting error messages that are beyond my capacity to fix.  The transcript from the terminal follows:

myuser at diglit-desktop:~$ ruby --version
ruby 1.8.7 (2010-01-10 patchlevel 249) [i486-linux]
myuser at diglit-desktop:~$ sudo gem install ruby-debug
[sudo] password for myuser: 
Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug:
