aeshan@aeshan-desktop:~$ sudo gem install mongrel
/usr/bin/gem:23: uninitialized constant Gem::GemRunner (NameError)

Somehow, rails isn’t happy on my eft laptop despite doing exactly what you describe above (which did work with appropriate replacements on my opensuse 10.2 server). Well, rails works, but then bombs when you try to generate scaffolding thusly:
philip@gus:~/workspace/gnarlyvines/winehandler$ ./script/generate scaffold appellation appellation
exists app/controllers/
exists app/helpers/
create app/views/appellation
exists app/views/layouts/
exists test/functional/
dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
create app/models/appellation.rb
create test/unit/appellation_test.rb
create test/fixtures/appellations.yml
/usr/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/active_record/connection_adapters/mysql_adapter.rb:389: [BUG] Segmentation fault
ruby 1.8.4 (2005-12-24) [i486-linux]

Ouch! Any ideas?

@Siddharth

I have yet to come across that problem. I haven’t used Xubuntu, but I can’t imagine why those 2 packages would have anything to do w/ each other. If you remove xserver-xorg, you will indeed lose your GUI… Hit up the #ubuntu irc channel on freenode.net, or file a bug report for Xubuntu because that just seems weird to me and I’m not sure how to get around that… Sorry…

When I execute sudo apt-get install libmagick9-dev it asks me to remove xserver-xorg. I’m using Xubuntu and the last time I did that, my GUI was gone.

Is there a way around removing this package?

Thanks a bunch for your effort.

It all worked smoothly except for some message while installing rmagick:

sh:wmf2eps command not found

The gem install still ended saying “Successfully installed rmagick..” and I see rmagick in output of ‘gem list –local’.
