Hi all,

I’m (well was) running rails on debian. After the update to rails 1.1.0  
newly  
created aps run great. But trying to start webrick for an old one makes  
me  
cry (see below).

Any docs on how to ‘migrate’ existing apps to the up and up?

Thanx n Grtz

Gerard.

`const\_missing’: uninitialized constant LoadingModule (NameError)

… and a lot more requires

Triple-Iso-Bifurcated-Krypton-Gate-MOS process …”

My $Grtz =~ Gerard;

:wq!

Have you upgraded all your plugins ? It seems to me one plugin might  
be attempting to do old-style dependencies support.

I had that often enough on Rails Engines that this page might help:  
[http://rails-engines.org/wiki/pages/Using+Engines+with+Edge+Rails](http://rails-engines.org/wiki/pages/Using+Engines+with+Edge+Rails)

Have a nice day !

The official engines plugin supports Rails 1.1 - just blow your old  
one away and reinstall it, or check the mailing list archives for  
detailed instructions.
