Cuando intente instalar rabbitmq-server en RHEL:

[ec2-user@ip-172-31-34-1XX ~]$ sudo rpm -i rabbitmq-server-3.3.5-1.noarch.rpm 
  error: Failed dependencies:
     erlang >= R13B-03 is needed by rabbitmq-server-3.3.5-1.noarch

[ec2-user@ip-172-31-34-1XX ~]$ rpm -i rabbitmq-server-3.3.5-1.noarch.rpm 
  error: Failed dependencies:
    erlang >= R13B-03 is needed by rabbitmq-server-3.3.5-1.noarch

No estoy seguro de por qué intentar instalar rpm no reconoce mi instalación de erlang desde que ejecuté$ erlda:

[ec2-user@ip-172-31-34-1XX ~]$ which erl
  /usr/local/bin/erl
[ec2-user@ip-172-31-34-1XX ~]$ sudo which erl
  /bin/erl
