[erlang-questions] erl -make exit status

[David Terrell]

% erlc -o ebin src/*.erl
src/my_test.erl:5: can't find include lib "eunit/include/eunit.hrl"
% echo $?
1

% cat Emakefile
{'src/*', [debug_info, {outdir, "ebin"}]}.
% erl -make
Recompile: src/my_test
src/my_test.erl:5: can't find include lib "eunit/include/eunit.hrl"
% echo %?
0

This is making it hard to use emake in my continuous integration
system... any suggestions?  Is emake considered production ready?
