[erlang-questions] rebar and the observer application.

I'm still very new, please forgive me if this is an easy question to answer.

I'm trying to use observer to view my application VM.  The application is
run as follows:

rel/xeuler1/bin/xeuler1 console
Exec: /home/red/projects/dev--/xeuler1/rel/xeuler1/erts-5.9/bin/erlexec
-boot /home/red/projects/dev--/xeuler1/rel/xeuler1/releases/1/xeuler1 -mode
embedded -config
-args_file /home/red/projects/dev--/xeuler1/rel/xeuler1/releases/1/vm.args
-- console
Root: /home/red/projects/dev--/xeuler1/rel/xeuler1
Erlang R15B (erts-5.9) [source] [64-bit] [smp:4:4] [async-threads:0]

Eshell V5.9  (abort with ^G)

I run up a second erlang instance with my observer application as follows:
erl -name observer -hidden -setcookie xeuler1 -run observer

The nodes are able to communicate:
(observer@REDACTED)1> net:ping(xeuler1@REDACTED).

However, when I try to connect to the remote node using the observer UI I
get the following output:
=ERROR REPORT==== 4-May-2012::13:22:17 ===
    node: 'xeuler1@REDACTED'
    call: {observer_backend,sys_info,[]}
    reason: {badrpc,

So, my understanding of the problem is that my reltool generated
environment doesn't have a deployed version of observer.  I've added it to
reltool.config the best I can understand it and a find rel/ | grep observer
does see observer related files in there.

If I try to run observer:start() from my actual xeuler1 VM then it hangs

Any advice on how I to debug this?
