Hi. I try to install Rforum and have it running.

I set RAILS\_GEM\_VERSION = ‘1.2.3’ in environment.rb  
But it may be useful for you to know that rails 2.0 is also installed on  
my machine

With the version 0.2 found zipped at rubyforge, I get the following  
error while typing:  
rake migrate

rake aborted!  
Regexp anchor characters are not allowed in routing requirements:  
/^[0-9]+$/

The error is the same when typing  
rake db:migrate

With the version from the darcs repository (  
[http://darcs.andreas-s.net/rforum](http://darcs.andreas-s.net/rforum) ), I get no error, but  
[http://localhost:3000/](http://localhost:3000/) is a blank page (through server is running for  
sure)  
and  
[http://localhost:3000/user/register](http://localhost:3000/user/register) is also a blank page.

Any idea that may help me?
