Redmine

An Addition: all got for now is:
"Application error
Rails application failed to start properly"

Ok, if i am right i need mongrel mongrel_cluster to run rails through apache?
Is that rquired?
I am running Ubuntu 8.04 server with rubygems 0.9.4-4.
I tried:
gem install --include-dependencies mongrel
Than i am asked which gem to install:
1. mongrel 1.1.5 (ruby)
2. mongrel 1.1.5 (x86-mswin32-60)
3. mongrel 1.1.5 (java)
4. mongrel 1.1.4 (x86-mswin32-60)
5. mongrel 1.1.4 (ruby)
6. mongrel 1.1.4 (java)

If i take 1. then comes up:

1. fastthread 1.0.1 (mswin32)
 2. fastthread 1.0.1 (ruby)
 3. fastthread 1.0.1 (i386-mswin32)

If i take 2. it ends up with an error:
Building native extensions. This could take a while...
ERROR: While executing gem ... (Gem::Installer::ExtensionBuildError)
ERROR: Failed to build gem native extension.

ruby extconf.rb install --include-dependencies mongrel
extconf.rb:1:in `require': no such file to load -- mkmf (LoadError)
from extconf.rb:1

Any suggestions?

The first thing you have to do, is to update your gem system: 0.9.4 is far TOO OLD. Please install gem 1.x

• you only want to test it, alone, or with a friend -> just run an instance, reverse proxy it in your apache. You're done.
• you want to setup a real-condition redmine -> install redmine, check it works alone. Install mongrel, mongrel cluster, test an instance of the cluster, then reverse proxy them to your apache.

Thy Thomas, i have installed rubygems 1.1.1 now, but gem install mongrel fails with this output:
Building native extensions. This could take a while...
ERROR: Error installing mongrel:
ERROR: Failed to build gem native extension.

/usr/bin/ruby1.8 extconf.rb install mongrel

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/fastthread-1.0.1 for inspection.

Maybe somybody else runs into it:
Seems that it's required to apt-get install build-essential on ubuntu hardy first.
