I don't think that's allowed:

   Readline is free software, distributed under the terms of the GNU
   General Public License, version 2. This means that if you want to use
   Readline in a program that you release or distribute to anyone, the
   program must be free software and have a GPL-compatible license. 
   
The Erlang licence is, I think, based on the NPL, and the NPL is
explicitly listed as not GPL compatible.
