Some Erlang packages (like ejabberd) use an Erlang script to do part of
the configure and build steps, thus we need a host Erlang.

This script may need to do some crypto stuff (e.g. to compute hashes,
or do https). In the Erlang world, all crypto stuff is implemented by
using oppenssl as the crypto backend.

So, we need a host Erlang with crypto support, and thus linked with
openssl.

Well, it can well wait for after the release, if you're not at ease with
it. Currently, we have no package that require Erlang, not even the host
Erlang.

However, since our host-erlang not being ssl-aware, it means no one is
really using it, and thus bumping should not cause a regressiopn for
anyone.

No one, but me, has complained so far. ;-)

Yann E. MORIN.
