Certain circumstances crash from Mailman.Email.parse!

[ebengt]

Greetings,

I get this crash
:load_failed, 'Failed to load NIF library: 'priv/eiconv_nif.so: cannot open shared object file: No such file or directory''
from Mailman.Email.parse!
But only when I run the program as an escript. If I start 'iex -S mix' and call Mailman.Email.parse! from the shell it is okay.

  Elixir 1.6.5 (compiled with OTP 19)

Mine is a very simple program and I have a workaround. So not really an issue, this is a FYI.
