mongrel2 says he can't read the PID file

Hi everybody,
    I just installed mongrel2 on Ubuntu 10.04 and followed the documentation
for installing and creating a first config file.
Here is the content of the config file:

from mongrel2.config import *

main = Server(
uuid="f400bf85-4538-4f7a-8908-67e313d515c2",
access_log="/log/access.log",
error_log="/log/error.log",
chroot="/var/www/mongrel2/",
default_host="localhost",
name="test",
pid_file="/run/mongrel2.pid",
port=37777,
hosts= [
Host(name="localhost", routes={
r'/tests/': Dir(base='tests/', index_file='index.html',
default_ctype='text/plain')
})
]
)

commit([main])


And when I do: m2sh start -db config.sqlite -h localhost, i get the
following message:

Please help fixing this little administration issue to allow me to start
enjoying mongrel2 hacking.

Alright, that's all fixed, I alos checked the code to reload and it
accepts thos parameters, so you are probably a version or so behind.  Go
ahead and grab:

http://mongrel2.org/home#download

To get the latest.  Then for now just make your logs directory /logs/ so
that you'll work with what we got until I release 1.0 tonight.

Let me know if you run into any other snags.

AHA! See how you have /log/ ?

This is all irrelevant, but this isn't:

See how that says "logs directory doesn't exist"?  Looks like we got a
bug that we expect "/logs/" explicitly.  Change your config to
/logs/access.log and /logs/error.log also do the stuff I mentioned in
the other email and you'll be set.  I'll fix this up too so that you can
actually use the config to do something different.

Logs and run directory must be under /var/www/mongrel2

They are both under /var/www/mongrel2

Are the owners of all of the directories consistent?  (is /var/www/mongrel2
owned by the same user as logs and run?)

They're all owned bu root, with rights 777

That's most likely wrong then.  Try this:

ls -ld /var/www/mongrel2

When I do that, my /var/www/mongrel2 is owned by the user mongrel2, not
root.

Ok, now do:

ls -l /var/www/mongrel2

When I do that, all the file inside are owned by mongrel2, not root.

You could also use nobody instead of mongrel2, but I like different
users for different services.  So try this:

mkdir -p /var/www/mongrel2/run
mkdir -p /var/www/mongrel2/logs
mkdir -p /var/www/mongrel2/tmp
chown -R mongrel2.users /var/www/mongrel2

Once you do that, mongrel2 will start up, chroot to /var/www/mongrel2,
become the user/group mongrel2/users, and it should work.

If not, do this:

cd /var/www/mongrel2

m2sh start -db config.sqlite -every

It'll run and then die, when it does, send a dpaste.de link with the
output of the log and I'll help figure out the cause.

One more thing, mongrel2.org and a few other services of mine basically
run this way and it works, so you should be looking at the logs and
trying to figure out you've done wrong.  Specifically look at the ERROR
log lines as they tell you lots of useful information for how to fix it.

Just thought worth mentioning that since the owner is root you should only
need the permissions to be 700

Those who do not understand Unix are condemned to reinvent it, poorly.
Any sufficiently recent Microsoft OS contains an ad hoc,
informally-specified, bug-ridden, slow implementation of half of Unix.

DId you make the logs and run directories?
