Ruby 1.9 and rubygems: should be able to use gem command?

Hi all,
I’ve installed ruby 1.9 from trunk and I used the --prefix option to
avoid conflicts with 1.8, like Dave T. advices here:
http://pragdave.blogs.pragprog.com/pragdave/2007/12/ruby-19right-fo.html

Everything seem to work splendidly, except for the “gem” command. The
new install has an empty gems cache of course, so all operations that
need to access that will try to bulk download the indexes from
http://gems.rubyforge.org

All index downloading fails with a unhelpful “Error fetching remote gem
cache: undefined method `[]=’ for nil:NilClass”

I started to try to find out where the failure occurs and it seems like
the guilty file is open-uri.rb (line 411), which is a call to the
meta_add_field of the Meta module (adding http heders I guess) where the
@meta inst var (a hash) is added to. The inst var isn’t set, so that’s
the nil in the above error message. Why is @meta nil? I’d say it’s
because the Meta module isn’t initialized properly, but I dont know why.

Before digging any deeper I wanted to ask you all: am I the only one
having issues with the “gem” command? Should it work? Any workarounds?
Am I missing something very basic?

Oh, versions:
gem -v => 1.0.1
ruby -v => ruby 1.9.0 (2008-01-21 revision 0) [i686-linux]

Platforms: MacOS X 10.5 and Ubuntu Feisty Fawn

Thanks for any pointers/comments!

I have the same behaviour, but only in trunk version. I suggest file
the bug on rubyforge
(http://rubyforge.org/tracker/?atid=1698&group_id=426&func=browse ,
first check if somone already did it) and use version tagged as
v1_9_0_0 (revision 14711). It should work.

It seems to be working for me–I just installed the revactor gem for
1.9. My setup may be a little different. I configured with
–program-suffix=19 so that ruby 1.9 can live in /usr/local without
conflict.

$ gem19 -v
1.0.1
$ ruby19 -v
ruby 1.9.0 (2007-12-25 revision 14709) [i686-linux]
$ uname -a
Linux tumbleweed 2.6.22-14-generic #1 SMP Tue Dec 18 08:02:57 UTC 2007
i686 GNU/Linux

(That’s Gutsy Gibbon)
