Redmine

Hi,
When running migrate_from_trac, after entering data for the various prompts I get the following error message:

Please install the sqlite3 adapter: `gem install activerecord-sqlite3-adapter` (
sqlite3 is not part of the bundle. Add it to Gemfile.)

Full trace and other details are given at the end.

If I then try running gem install activerecord-sqlite3-adapter I get the following error message:
ERROR: Could not find a valid gem 'activerecord-sqlite3-adapter' (>= 0) in any
repository
ERROR: Possible alternatives: activerecord-jdbcsqlite3-adapter, activerecord-s
lserver-adapter, activerecord-spatialite-adapter, activerecord-dbslayer-adapter
activerecord-nulldb-adapter

I'm floundering a bit as I am new to Ruby and Redmine.
Any assistance greatly appreciated.

Many thanks,
Tim
