     Is the thread
     http://www.nabble.com/error-connecting-to-rabbitmq-node-td19498782.html
     of any help?

     i.e. are you perhaps running a manually built Erlang?

     One way to find out is to run erl and call code:get_path(), e.g.

     $ erl
     Erlang (BEAM) emulator version 5.6.5 [source] [smp:4] [async- 
threads:0] [hipe] [kernel-poll:false]

     Eshell V5.6.5  (abort with ^G)
     1> code:get_path().
     [".","/usr/lib/erlang/lib/kernel-2.12.5/ebin",
      "/usr/lib/erlang/lib/stdlib-1.15.5/ebin",
     ...
      "/usr/lib/erlang/lib/rabbitmq_server-1.5.4/ebin",
     ...]

     If the result does not have /usr/lib/erlang/lib/... as the paths  
then you are not running the debian-packaged Erlang and either need to  
switch to that, or add some suitable symlinks, or tweak Erlang's load  
path.

     If the result *does* have /usr/lib/erlang/lib but there is no  
sign of rabbitmq_server-* in the list then the package didn't install  
properly.

     If the result looks as above but rabbit still won't start then  
something  weird is going on.


     Matthias.
     PS: Next time please email the rabbitmq-discuss list. You'll get  
an answer quicker that way and other users benefit from the findings.



thanks for the help!

turns out that there were 2 version of erlang installed on that  
computer. i386 and x86_64. i was installing the 64bit version of  
rabbit, but the default erl was 32 bit. if i removed the 32bit version  
and symlinked /usr/lib64/erlang/bin/erl to /usr/bin/erl, the server  
starts.

too bad erlang doesn't give more helpful error messages. like  
'rabbitmq not found in /usr/lib/erlang/lib'.
