Yes.
I did a post about that just the other day.
if you know how, you can edit the erts/configure.in a rebuild erlang.
If you can live with 32-bit or build from git Dan also had some nice ways around this.

I will see if I can produce some easy instructions on how to start with cl.
But in this case it was never possible to get started ;-) 

Thanks
