Bug #3332: r27953: gem install causes "uninitialized constant Gem::Commands::InstallCommand"
http://redmine.ruby-lang.org/issues/show/3332

Author: Gregory Brown
Status: Open, Priority: Normal
ruby -v: ruby 1.9.3dev (2010-05-22 trunk 27953) [x86_64-darwin10.3.0]

Building from http://svn.ruby-lang.org/repos/ruby/trunk at r27953 causes gem install to fail on both Mac OS X 10.5 and 10.6.

Steps to reproduce follow:

Build from SVN at the above revision in the standard way:

autoconf
./configure
make
make install

Then run the following:

$ gem install -prawn -V --debug
