I have recently upgraded from Ruby 1.8.7 to 1.9.2p180 on Fedora. After a
period of time, a day perhaps, the installation goes corrupt. It works
perfectly fine initially then everything fails. I am rolling this from
source with typical ./configure/make/make install type process. A few
examples:

#irb
<internal:lib/rubygems/custom_require>:29:in `require': closed stream
(IOError)
  from <internal:lib/rubygems/custom_require>:29:in `require'
  from /usr/lib/ruby/1.9.1/irb.rb:13:in `<top (required)>'
  from <internal:lib/rubygems/custom_require>:29:in `require'
  from <internal:lib/rubygems/custom_require>:29:in `require'
  from /usr/bin/irb:9:in `<main>'



# gem list

What does one do to even troubleshoot this let alone fix it?
