I just tried to install 1.8.7.p334 on a CentOS-5 host that previously
ran 1.8.7p302. I downloaded and built ruby from source and then used
checkinstall to build a local rpm package from which I installed the VM
using rpm -U. All these steps completed without error:
$ ruby --version
ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-linux]
However, when I attempt to run gem I get this error:
$ gem

I then tried to update RubyGems by downloading and installing from
source. However, when I attempt to run ruby setup.rb I get this error:
./lib/rubygems/dependency_list.rb:7:in require': no such file to load -- tsort (LoadError) from ./lib/rubygems/dependency_list.rb:7 from ./lib/rubygems.rb:29:inrequire’
from ./lib/rubygems.rb:29
from setup.rb:24:in `require’
from setup.rb:24
Searching for tsort.rb finds it in the expected (for me) place:
$ find / -name tsort.rb
/usr/lib/ruby/1.8/tsort.rb
the question I have is: What have I borked and how do I fix it?
