Hi guys,

Very new to RedMine, an in no way a Ruby/RoR dev, so I could be mistaken here.

Fired up a new Ubuntu 12.04 53 VM for a fresh installation.

I followed the excellent guide here (so will just rehash my post there).

When I get to this point:

$ sudo RAILS_ENV=production rake db:migrate

I get hit up with this error:
Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (mysql2 is not part of the bundle. Add it to Gemfile.)
Tasks: TOP => db:migrate => environment
(See full trace by running task with –trace)

I’m following this up with:

$ sudo gem install activerecord-mysql2-adapter mysql2
Successfully installed activerecord-mysql2-adapter-0.0.3
Building native extensions. This could take a while…
Successfully installed mysql2-0.3.11
2 gems installed
Installing ri documentation for activerecord-mysql2-adapter-0.0.3…
Installing ri documentation for mysql2-0.3.11…
Installing RDoc documentation for activerecord-mysql2-adapter-0.0.3…
Installing RDoc documentation for mysql2-0.3.11…

& try running again the initial command, but the problem remains.

I then try to check the [setup] (? sorry – I’m not a ruby dev):

$ sudo bundle install | grep -i sql
Using mysql (2.8.1)

After a bit of digging, I think I found a bug & a solution to said bug – I can be wrong, but this allowed be to sake a step forther.
In the Gemfile, I searched for references to “mysql” & commented out & replaced (based on the next portion of same file)

# gem “mysql”
gem “mysql2″, “~> 0.3.11″

Ran `sudo bundle update` & then the buggy command again & managed to proceed.

This could be some sort of dependency issue or a typo in the Gemfile - i.e. ruby 1.8.x vs 1.9.x - not sure.
