The configure script doesn't look for it directly.  It runs the compiler 
on a simple test file to see whether including jni.h works.  If the 
header file is installed somewhere that the compiler normally looks, 
then everything works properly.  If not, then you have to modify the 
flags that the compiler uses to modify its header search path.  So 
something like

  configure CPPFLAGS=-I/where/ever/it/is

will probably work.  Of course, you need to replace /where/ever/it/is 
with the actual directory where jni.h is installed.
