Redmine

The Rails version that comes with the releases is the required Rails version.
For 0.9.x, it's Rails 2.3.5. More details here: RedmineInstall.

Thanks for your reply Jean-Philippe.

Sure I've read the RedmineInstall page. I asked this because on our server, there is one Redmine 0.8.4 install which is actually in production and a second "small" one for doing tests.

I wanted to test the 0.9.2 upgrade against the second one and I first upgraded Rails to 2.3.5.
That's when I stumbled upon dependency problems because of the mysql helper not being included in Rails anymore and needing to be installed separately. As it required some compilation, I had to find a Ruby 1.8.7 development package that matched the installed Ruby (thanks to SUSE/Linux packages discrepancy) and also a development package for MySql.

All dependencies issues are solved now, but as my second install (still) doesn't work anymore, I was wondering how it was that the production install kept working while there were still these dependencies issues with Rails. I assume Rails that comes with Redmine releases (Rails 2.1.2 in Redmine 0.8.4 case) takes precedence...

All rails applications will use the version of rails in the app's /vendor/rails directory if it exists.

This takes precedence over the system-wide gem install. In fact this is true for all gems, anything in /vendor takes precedence.

Thanks for the clarification, Jeffrey.
I must say I don't know much about Ruby and Rails, and it's... special :-)
