I actually followed it apart from the export command so after using export path command also the error still pops up that -> configure: error: Erlang/OTP interpreter (erl) not found but required
Complete scenario went something like this:
[ec2-user@REDACTED ~]$ kerl list builds
17.1,erlang-17.1
17.1,erl
[ec2-user@REDACTED ~]$ export PATH=$PATH: ~/kerl/17.1/bin/erl
-bash: export: `/home/ec2-user/kerl/17.1/bin/erl': not a valid identifier
[ec2-user@REDACTED ~]$ export PATH=$PATH:~/home/ec2-user/kerl/17.1/bin/erl
[ec2-user@REDACTED ~]$ erl
-bash: erl: command not found
[ec2-user@REDACTED ~]$ kerl active
No Erlang/OTP kerl installation is currently active
[ec2-user@REDACTED ~]$ export PATH=$PATH:~/home/ec2-user/kerl/17.1/bin/erl
[ec2-user@REDACTED ~]$ . ~/kerl/17.1/activate
[ec2-user@REDACTED ~]$ kerl active
The current active installation is:
/home/ec2-user/kerl/17.1
[ec2-user@REDACTED ~]$ erl
Erlang/OTP 17 [erts-6.1] [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]
Eshell V6.1 (abort with ^G)
1> q().
ok
2> [ec2-user@REDACTED ~]$ cd downloads/
[ec2-user@REDACTED ejabberd-17.03]$ cd ejabberd-17.03/
[ec2-user@REDACTED ejabberd-17.03]$ ./configure

You need to be root to perform this command.
