mochijson2 module conflict

[kxepal]

Just have tried to make rel for rcouch and it had failed with the error:

ERROR: generate failed while processing /home/kxepal/projects/refuge/rcouch/rel: {'EXIT',{{badmatch,{error,"Module mochijson2 potentially included by two different applications: mochiweb and rabbit."}},
             [{rebar_reltool,generate,2,[]},
              {rebar_core,run_modules,4,[]},
              {rebar_core,execute,5,[]},
              {rebar_core,process_dir1,6,[]},
              {rebar_core,process_each,5,[]},
              {rebar_core,process_dir1,6,[]},
              {rebar_core,process_commands,2,[]},
              {rebar,main,1,[]}]}}
    make: *** [generate] Error 1

Yes, I have RabbitMQ also installed. Google told me that the only way to solve it - rename conflict module by adding project's prefix to his name, but for which side I should do this?

mmm is rabbitmq installed system-wide?

yes, it's installed via system package manager

hm..I'd uninstall RabbitMQ and got the new error that totally shouldn't be related to rcouch (do you have ldap support?):

May be there is something wrong with my system?

Solved problem by adding next lines into rel/reltool.config as was suggested in ML:

        %% conflicts
        {app, rabbit, [{incl_cond, exclude}]},
        {app, tsung, [{incl_cond, exclude}]},

But I feel this is a bit wrong way to go, since it's not a deal to maintain blacklist of conflicted projects...

[benoitc]

something should be done to detect the external deps somehow.... or rather all erlangs apps should be installed as a release ...

Hm..what do you think about next one? A bit verbose and explicit, but hangs no more due to conflicted modules both for rabbit and tsung:

@kxepal I pushed the change above in the fix/20 branch to make some tests. Sounds good anyway, thanks for the patch!
