I am trying to prepare source archive using

With Ruby 2.0.0 rev38184 as as BASERUBY, however with no luck:

Alternatively, there could be used --disable-gems I think.

Those patch don't fit this issue because ruby 2.0 still can't be use for 
BASERUBY of Ruby 1.9.3 or prior.
This is an issue of rubygems.

I still don't understand what is the issue, why older ruby works and 2.0 
does not work. So keep the '-I.' and add '--disable-gems' could fix the 
issues as well.

> This is an issue of rubygems.

I would not blame RubyGems. Yes, they are doing more then they used to 
do, but requiring wrong rbconfig is definitely not issue of RubyGems, 
but issue of the build configuration. I would say that change in 
RubyGems just made the issue apparent, so fix in RubyGems will be fix in 
wrong place IMO.

RubyGems uses the information in rbconfig.rb like 
RbConfig::CONFIG["libdir"].
Previous gems works even if RbConfig::CONFIG["libdir"] is nil,
but the one bundled with 2.0 raises exception.
So 2.0 doesn't work.

-I is not acceptable because it doesn't load correct rbconfig.rb.
--disable-gems is not acceptable because it doesn't work for 1.8.

Ah, so the presumably wrong rbconfig.rb is correct one. Wouldn't be 
safer to not relay on rbconfig at all and take the information from some 
other place instead, e.g. config.status?

Yes, such incomplete rbconfig.rb is also a correct one to make a 
package.

> Wouldn't be safer to not relay on rbconfig at all and take the information from 
some other place instead, e.g. config.status?

Yeah, it can be, and simply it can take info from reading and parsing 
rbconfig.rb instead of loading.
But for example ruby 1.9.3's build process can't be changed, so this 
must be fixed by ruby 2.0's side.

It seems that the `ruby -I. ./tool/compile_prelude.rb ./prelude.rb 
miniprelude.c` command is executed from the temporary directory with 
fresh sources. However, since there is added current directory '.' into 
the load path, the rbconfig.rb available there gets precedence instead 
of the rbconfig.rb of BASERUBY. Unfortunately, that rbconfig.rb contains 
just some rubbish.

The attached patch might fix the issue, but I am not sure what it 
breaks, since the original commit message introducing this flag (r14271) 
is not overly descriptive :/

Issue #7541 has been updated by drbrain (Eric Hodel).

Category set to lib
Target version set to next minor

This appears to be a chicken and egg problem, but I don't have enough 
information to know how to solve it.

Should RubyGems know not to load when run as BASERUBY? How should 
RubyGems determine this?

I am trying to prepare source archive using

 tool/make-snapshot tmp

With Ruby 2.0.0 rev38184 as as BASERUBY, however with no luck:

Subject changed from Can't use Ruby 2.0.0 as as BASERUBY to Can't 
use Ruby 2.0.0 as as BASERUBY

=begin
I was able to build ruby:

 $ tool/make-snapshot tmp branches/ruby_2_0_0

using

 ruby 2.0.0dev (2013-02-08 trunk 39161) [x86_64-linux]

So this is probably resolved. Can anybody confirm?
