Trying to compile a test project using objective c and autoconf/automake I get 
the following error:

gmake[2]: Entering directory `/home/pupeno/src/testtest/debug/src'
source='/home/pupeno/src/testtest/src/testtest.m' object='testtest.o' 
libtool=no depfile='.deps/testtest.Po' tmpdepfile='.deps/testtest.TPo' 
@OBJCDEPMODE@ /bin/sh /home/pupeno/src/testtest/depcomp cc -DHAVE_CONFIG_H 
- -I. -I/home/pupeno/src/testtest/src -I.. -c -o testtest.o `test -f 
'/home/pupeno/src/testtest/src/testtest.m' || echo 
'/home/pupeno/src/testtest/src/'`/home/pupeno/src/testtest/src/testtest.m
/bin/sh: line 1: @OBJCDEPMODE@: command not found

What is this OBJCDEPMODE and to what (and how) should I set it ?
Are there any work on making a canned set of macros of objc ?

Thanks
