[web-devel] Yesod beginner

[anthropornis]

Hello,

I was following the "Yesod in Five Minutes Instructions" and I had a 
couple of bumps in the road.

The first one was when trying to do step 6, I get the following terminal 
output:
     unrecognized option `--only-dependencies'

After ignoring that for the moment, I proceeded to trying to run the 
devel server and I get this terminal output:
     yesod: user error (At least the following dependencies are missing:
     persistent-postgresql ==0.5.*)

I'm guessing the second error may be related to the first, maybe 
persistent-postgresql was one of those dependencies that was supposed to 
be installed?

I did create the Postgres databases and user specified in the Yesod app 
config file.

I'm using this PPA on Ubuntu 11.04 64-bit, as the repo version of the 
Haskell Platform seems to be broken:

Thanks for any insight.
