compiling problems on mac os 10.3

hi!

im trying to compile mad_ruby 1.2 on mac os 10.3. i have the stable 
apache2,
apache2-dev and apr packages installed from fink. if i run make i get 
this:

cc -dynamic -bundle  -L/sw/lib -o mod_ruby.so mod_ruby.o ruby_config.o 
apachelib.o array_header.o table.o connection.o server.o request.o  \
         -lruby -ldl -lobjc
ld: Undefined symbols:
_ap_add_cgi_vars
_ap_add_common_vars
_ap_add_version_component
_ap_hook_access_checker
_ap_hook_auth_checker
_ap_hook_check_user_id
_ap_hook_child_init
...


does anybody have an idea what could go wrong here?

i used configure like this:
./configure.rb --with-apxs --with-apr-includes=/sw/include/apr-0

thanks a lot!

ciao!
