Me and Martin just had this problem in Jungerl and tracked it down: in
R9B-0, the 'erlc' command sometimes uses the stand-alone-erlang 'ecc'
as the backend. Unfortunately, ecc is not fully compatible -
include_lib doesn't work properly.

It would be great if this can be fixed in the upcoming R9B update,
even if just to disable ecc-in-erlc until it can be fixed!

In Jungerl, I just checked in an ugly workaround to add '-pa /fake'
always as an argument to erlc, since this trips a flag in erlc
(erts/etc/common/erlc.c) to say that it won't use ecc as the backend.

The offending line in our case was:

  -include_lib("kernel/src/disk_log.hrl").

And we see that Vance Shipley has had the same problem with an eva
include.

Cheers,
