Ugh. Yes, in R14A, the type is ets:tid(), and in previous versions it's
tid(). They decided not to try and migrate gently... Another example is
that it would seem dict:dictionary() only exists from R14A onwards and
was dict() previously. Weirdly, that issue only shows up when you
actually run "make dialyze" whereas the previous one breaks the
compilation. Very strange.

I've bumped the version requirements for the specs to R14A - if you pull
and update, it should now build for you.

Yeah, it should pick it up from the enviroment too -
"make -j USE_SPECS=false" should work.
