Hello,

This issue seems not to be fixed completely.
"gem install rbtree" still hit this issue.
It reproduces on both trunk and 2.0.0-p0.


$ gem install rbtree

Bug #7698: RubyGems 2.0 has an incompatibility about installation of extension libraries
https://bugs.ruby-lang.org/issues/7698#change-36998

Author: mrkn (Kenta Murata)
Status: Assigned
Priority: High
Assignee: drbrain (Eric Hodel)
Category: lib
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2013-01-14 trunk 38812) [x86_64-linux]


The current rubygem included in ruby-head has an incompatibility about installation of extension libraries.
This incompatibility makes `make install` to be failed because the current gem doesn't separate build, source and install directories.

This is reported as a bug of bigdecimal's gemspec in #7344 firstly, but Tadashi Saito pointed out it also can be reproduced in other gems including extension libraries, such as decimal.gem.
I think this incompatibility will make gem-developers to be in trouble after ruby-2.0 is released.
So this should be resolved before ruby-2.0 is released.
