Yes you do have ffcall. It says so in the log file. But you don't have 
a proper libobjc library:

checking for callback.h... yes
checking "for forwarding callback in runtime"... no
checking "FFI library usage"... none

GNUstep requires ffcall or libffi and proper libobjc hooks to do
                                                                
-----------------------------
invocations and DO.
Make sure one of these libraries is installed and you have a proper
libobjc library. Otherwise DO will not be compatible with other


(underlines are mine).
