Subject: RubyGems 0.9.5 ignoring spec.bindir

Hello,

I want to make a gem for a small (< 200 lines) project of mine.  The
entire project is stored in one Ruby source file, so I don't want to
create a separate "bin/" directory.  I read about RubyGems' bindir
parameter which allows you to override the "bin/" directory requirement
and basically put your executable anywhere inside your project
directory.

The problem is that RubyGems 0.9.5 is ignoring my

  spec.bindir = '.'

assignment and looking for a "bin/" directory instead.

I tried using

  spec.bindir = nil

but that does not work either.

Here is a complete example to reproduce the problem:

$ ls -l
-rw-r--r-- 1 sun sun 371 2007-12-09 18:53 Rakefile
-rwxr-xr-x 1 sun sun  39 2007-12-09 18:53 foobar*

$ ./foobar
hello world

$ cat foobar
#!/usr/bin/env ruby
puts "hello world"

$ cat Rakefile
require 'rake/gempackagetask'

spec = Gem::Specification.new do |s|
  s.name        = 'foobar'
  s.version     = '0'
  s.summary     = 'summary'
  s.files       = 'foobar'
  s.executables = 'foobar'
  s.bindir      = '.' # our executable is not inside 'bin/'
end

# does nothing unless block given, dunno why...
Rake::GemPackageTask.new(spec) do end

$ rake -T
(in /home/sun/lab/gemspec)
rake clobber_package  # Remove package products
rake gem              # Build the gem file foobar-0.gem
rake package          # Build all the packages
rake repackage        # Force a rebuild of the package files

$ rake gem
(in /home/sun/lab/gemspec)
  Successfully built RubyGem
  Name: foobar
  Version: 0
  File: foobar-0.gem

$ gem install pkg/foobar-0.gem -i my_out_dir
ERROR:  While executing gem ... (Errno::ENOENT)
    No such file or directory -
/home/sun/lab/gemspec/my_out_dir/gems/foobar-0/bin/foobar

See this error?  Why is it looking for a "bin/" directory when I
assigned spec.bindir?!

Thanks for your consideration.
