Don't know what's going on here, and I can't crosscheck it since I don't 
own a linux box. maybe some variable is not or wrong set.

One thing you can do is to go to line 33 of the script and move the # sign 
one line lower. Now you see all the compilers output in your console like 
this:

checking for ffi.h... cc -E -traditional-cpp  -fnext-runtime 
-DNeXT_RUNTIME conftest.c >/dev/null 2>conftest.out
conftest.c:2: ffi.h: No such file or directory
#include "confdefs.h"
#include <ffi.h>
no
checking for forwarding callback in runtime... no
checking for callback.h... cc -E -traditional-cpp  -fnext-runtime 
-DNeXT_RUNTIME conftest.c >/dev/null 2>conftest.out
conftest.c:2: callback.h: No such file or directory
#include "confdefs.h"
#include <callback.h>
no
checking FFI library usage... none
preflight.sh: warning: No ffcall interface library found

        ! GNUstep requires the ffcall library to do invocations and DO
        ! Make sure this library is installed (see installation 
instructions)
        ! Otherwise DO will not be compatible with other systems
