Redmine

I needed to upgrade ruby to a version greaer that 1.8.x as I need to install the Backlog plugin. I installed ruby but for some reason Redmine kept picking up the old version.

I ended up uninstalling Ruby and reinstaling using rvm. And Regmine picked the correct version but passenger was problematic. Now after spening time stuffing thing up I am getting this error

I'm don't know what it all means. I have two versions of passenger 4.0.27 and 4.0.26 both produce the same error.

any help or pointers would be welcomed

thanks
