I just spent 2 days figuring this out but it seems the issue is one of 
the gems in the vendor/gems directory.

Machine is a Mac Mini G4 1.25ghzisch with 10.4.6isch? (Anybody else 
dislike the new intel mac's? ;-) )

I completely removed ruby & made sure it was using the macports version 
and after pretty much nuking every single gem and gem install typo on a 
empty directory stll got this:

lhc:/var/www/atomlab root# rake db:create RAILS_ENV='production'
(in /private/var/www/atomlab)
config.gem: Unpacked gem calendar_date_select-1.15 in vendor/gems has no 
specification file. Run 'rake gems:refresh_specs' to fix this.
config.gem: Unpacked gem coderay-0.8.260 in vendor/gems has no 
specification file. Run 'rake gems:refresh_specs' to fix this.
config.gem: Unpacked gem htmlentities-4.0.0 in vendor/gems has no 
specification file. Run 'rake gems:refresh_specs' to fix this.
config.gem: Unpacked gem json-1.1.3 in vendor/gems has no specification 
file. Run 'rake gems:refresh_specs' to fix this.
[BUG] cross-thread violation on rb_gc()
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

So I went ahead and mv vendor/gems/* /tmp/gems/

Of course now I was getting:
lhc:/var/www/atomlab root# rake db:create
(in /private/var/www/atomlab)
rake aborted!
no such file to load -- coderay

After
gem install coderay htmlentities json calendar_date_select

*drumroll*
lhc:/var/www/atomlab atom$ rake db:migrate RAILS_ENV='production'
(in /private/var/www/atomlab)
==  InitialSchema: migrating 
==================================================
-- create_table(:users)
    -> 0.0712s
-- create_table(:articles)
    -> 0.1310s
-- add_index(:articles, :permalink)

We have migrationage!

Oh I then ran
lhc:/var/www/atomlab atom$ sudo rake gems:unpack
