whenever possible... I agree

I do have given a try to
-I/System/Library/Frameworks/JavaVM.framework/Headers/
and it works...
a the condtion to change the linking instructions (see below).

Bingo !
the optional.jar was missing !
Now using the ant shipping with JBuilderX (1.5.4)

so the C/pljava/Makefile is now

#-----------------------------------------------------------------------

#    Makefile for pljava

NAME    := pljava

include $(MODULEROOT)/Makefile.global

ifeq ($(PORTNAME), win32)
         DLL_BUILD := 1
else
ifeq ($(PORTNAME), cygwin)
         DLL_BUILD := 1
         override CPPFLAGS := -DCYGWIN $(CPPFLAGS)
else
ifeq ($(PORTNAME), darwin)
         override CPPFLAGS :=  
-I/System/Library/Frameworks/JavaVM.framework/Headers/ $(CPPFLAGS)
else
         JRE_INCL := $(PORTNAME)
         ifeq ($(host_cpu), i686)
                 JRE_LIB := lib/i386/client
         else
                 JRE_LIB := lib/$(host_cpu)/client
         endif
endif
endif
endif

ifdef DLL_BUILD
         JRE_INCL := win32
         JRE_LIB  := bin/client

         # This works but is not very nice since it affects all
         # DLLTOOL invocations in Makefile.shlib. A custom flag
         # is requested from postgres.
         #
         override DLLTOOL := $(DLLTOOL) --add-stdcall-alias
endif

ifdef USE_GCJ
         override CPPFLAGS := -DGCJ $(CPPFLAGS)
         SHLIB_LINK = $(BE_DLLLIBS) -lgcj -lwsock32
else
ifeq ($(PORTNAME), darwin)
         SHLIB_LINK = $(BE_DLLLIBS) -L. -framework JavaVM
else
         override CPPFLAGS := -I$(JDK_HOME)/include  
-I$(JDK_HOME)/include/$(JRE_INCL) $(CPPFLAGS)
         SHLIB_LINK = $(BE_DLLLIBS) -L. -L$(JDK_HOME)/jre/$(JRE_LIB)  
-ljvm
endif
endif

... no changes after that

The change
#ifdef DARWIN
         #include <JavaVM/jni.h>
#else
         #include <jni.h>
#endif
shoudl not be necessary anymore.

Now everything compiles,
regarding the tests : do you have any more precise instructions to  
follow than what is in the README ?
