[erlang-questions] erlrt and eunit

My bad! I have mytest.erl and test.erl, almost same except different
module names. When editing the post, I used the error report for
test.erl. Sorry for the confusion.

I installed eunit-2.0 using erlrt. I am able to see it under
erlrt/erlang/lib. (Starting with the minimum install, erlrt also
picked up compiler-4.3.12, which I assume was due to dependency.)

Here is the list of files in erlrt/erlang/lib/eunit-2.0:

eunit-2.0/
eunit-2.0/include
eunit-2.0/include/eunit_test.hrl
eunit-2.0/include/eunit_off.hrl

Here is mytest.erl.

-module(mytest).
-compile(export_all).
-include_lib("eunit/include/eunit.hrl").

my1_test() -> ?assert(1 == 1).
my2_test() -> ?assertNot(0 == 1).

And here is the output.

Erlang (BEAM) emulator version 5.4.13 [source] [hipe] [threads:0]

2> mytest:test().

Thanks for your help.
