Objective C on Mac OS X

all,

i am currently porting some autotoolized c++ code to mac os x, it all works 
fine. however, when i try to integrate some objective c code, i get a bunch 
of errors i don't understand.

i did set OBJC=gcc, OBJCFLAGS='-O2 -g' and OBJCLDFLAGS='-lobjc' in my 
configure.ac. 

when i now try to call automake, it complains:

/sw//share/automake-1.7/am/depend2.am: am__fastdepOBJC does not appear in 
AM_CONDITIONAL

so i tried to set am__fastdepOBJC_TRUE and am__fastdepOBJC_FALSE in 
configure.ac, but this didn't help either. automake now generates a Makefile, 
but compilation stops at calculating the dependecies:

source='/Users/wagnerm/cvs/dwarf/src/services/Speaker/main.m' object='main.o' 
libtool=no \
depfile='.deps/main.Po' tmpdepfile='.deps/main.TPo' \
 /bin/sh /Users/wagnerm/cvs/dwarf/depcomp \
g++ -DHAVE_CONFIG_H -I. -I/Users/wagnerm/cvs/dwarf/src/services/Speaker 
- -I../../..     -g -O2 -c -o main.o `test -f 
'/Users/wagnerm/cvs/dwarf/src/services/Speaker/main.m' || echo 
'/Users/wagnerm/cvs/dwarf/src/services/Speaker/'`/Users/wagnerm/cvs/dwarf/src/services/Speaker/main.m
depcomp: Variables source, object and depmode must be set
make: *** [main.o] Error 1

if i disable dependency tracking using

AUTOMAKE_OPTIONS = no-dependencies

it all works, but i think disabling dependency tracking is no good solution 
either.

can anyone help out? i have automake 1.7.3 (compiled from source), libtool 
1.4.2 (from fink) and autoconf 2.54 (from fink).

thanks in advance,
martin
