Error on build.sh

[jannone]

I got this error when trying to run build.sh:

{"init terminating in do_boot",{undef,[{make,all,[]},{init,start_it,1},{init,start_em,1}]}}

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()

EDIT: tested with both master and 2.1.13 branches. Same error. My ejabberd is version 2.1.10, running on Ubuntu 12.04 (I'm not allowed to upgrade it).

@jannone are u using the 2.1.x branch of this code?
