Strictly speaking this is a third party issue and already reported as
http://rubyforge.org/tracker/index.php?func=detail&aid=27087&group_id=126&atid=575
at 2009-09-10 but is still open with no response.

I'll post this so that other core developpers have chance to know the issue.

fyi, this is a clean install (configure && make && sudo make install) and rubygems-update 1.3.5 is not installed.

gem list

*** LOCAL GEMS ***

minitest (1.5.0)
rake (0.8.7)
rdoc (2.2.2)

I'm not sure what to do about this yet.

gem_prelude.rb provides a fake rubygems.rb, but require 'rubygems/specification' does not cause the real rubygems.rb to be loaded.

This causes the errors.

The workaround is to assume that Gem::Specification is available, because require 'rubygems' provides it instead of requiring 'rubygem/specification'.

Hi, Nobu

Are you willing to handle this ticket?
If you are, are you willing to fix this issue?
If you are, will the fix be included in 1.9.2?

Hi,

I decide this issue as WONTFIX for 1.9.2.
As Eric said, do not require "rubygems/specfication" directly.

The workaround is to assume that Gem::Specification is available, because require 'rubygems' provides it instead of requiring 'rubygem/specification'.

This issue should be fixed in 1.9.3, by the approach of nobu's patch
in #3140.

This seems to be fixed in ruby trunk:
