undef gen_leader:start_link

Sorry if this issue duplicates smth. Can't start gproc with gproc_dist for master or latest 0.6.1

(a@localhost)1> application:set_env(gproc, gproc_dist, all).
ok
(a@localhost)2> application:start(gproc).
{error,{{shutdown,{failed_to_start_child,gproc_dist,

It might be because gproc doesn't automatically fetch gen_leader. The rebar.config.script file checks for the OS env variable GPROC_DIST. If true, it adds gen_leader to deps, otherwise not.

[netDalek]

No, I've set GPROC_DIST and gen_leader pulled successfully. Surprisingly but rebar compile for the whole project doesn't generate gen_leader.beam file. I have to run rebar compile inside deps/gen_leader
