Version: ruby 1.9.1p0 (2009-01-30 revision 21907) [i686-linux]
Is there something wrong with this version?
1:
Dir.foreach("/tmp") {|f| puts f if File.directory?(f) }
– it just prints ‘.’ and ‘…’
Have you checked to see if you do have directories inside /tmp other
than ‘.’ and ‘…’?
2:
puts Dir.tmpdir
Dir.mktmpdir { |i| puts i }
– it says 'undefined
As for “undefined method” you’re quite right, I can’t find Dir#tmpdir
defined anywhere either, and yet it’s in the docs…what’s the deal
guys?

Dir.foreach("/tmp") {|f| puts f if File.directory?(f) }
– it just prints ‘.’ and ‘…’
Dir.foreach("/tmp") {|f| puts f if File.directory?("/tmp/#{f}") }
or
Dir.chdir("/tmp") do
Dir.foreach(".") {|f| puts f if File.directory?(f) }
end
or
Dir.glob("/tmp/") {|f| puts f if File.directory?(f) }
or
Dir.glob("/tmp//") {|f| puts f}
or
puts Dir.glob("/tmp//")
or
puts Dir["/tmp//"]
The glob-ones will not include hidden directories or . and … and they
will
print the full-path to the dir (though you could also use chdir with
glob, if
you don’t want the full path).

Yeah. The core rdoc on http://www.ruby-doc.org/ has a pitfall that it
includes the standard libraries as well. (Nobody separated out the
standard libraries from that.)
If you want to know what’s in the core, getting a copy of PickAxe is a
better bet.
