May be somebody has a clue, why I get these errors below, while trying
to migrate.
Any help is very appreciated!

I was trying to experiment a litte bit with redMine (www.redmine.org).
But I can only install it locally. On a system with already a
mongrel_cluster running, I get strange errors, already while trying to
start the migration rake db:migrate RAILS_ENV="production"
Thank you for your reply.
Sorry but redmine has a hellot of migrations.
I also think, this come's from another part because, I tried it also
in the console to type in some commands... same error.
I guess something with the database connection is wrong, is there a
way to test the database connection?
thnx

I believe the issue stems from incompatible versions of Ruby libraries. Are you using the same versions of Rails, gems and mysql adapter on both machines?
With the help of a redmine developer, I found the final solution.
Seems, that mysql adapter was not or false installed.
To fix this I did (re)install the mysql gem
