[debian-7] has Erlang R15 by default, fails build

[janl]

ERROR: OTP release R15B01 does not match required regex R16B03-1|17|18

[janl]

still installs R15 with the backports.

Description-en: Concurrent, real-time, distributed functional language
 Open Source Erlang is a functional programming language designed at
 the Ericsson Computer Science Laboratory.
 .
 Some of Erlang main features are:
  * Clear declarative syntax and is largely free from side-effects;
  * Built-in support for real-time, concurrent and distributed programming;
  * Designed for development of robust and continuously operated programs;
  * Dynamic code replacement at runtime.
 .
 The Erlang distribution also includes OTP (Open Telecom Platform) which
 provides a rich set of libraries and applications.
 .
 This package is a dummy package which will install Erlang/OTP runtime,
 applications, sources, code examples and the Erlang editing mode for Emacs.

ah, uninstall takes more than I had

[janl]

hm, no.

what am I missing here?

1. no erl
2. show erlang/wheezy-backports, shows R17 (I think)
3. install erlang/wheezy-backports, log shows R15 (I think)
