MacOSX install problem

Dear ROOTers

Now I try to install root v5.14.i from source,not binary.
In directory “Users/kimiaki/root_v5_14i/root”,

./configure --prefix=/Users/kimiaki/cern/ROOT/root_5_14
make
But,I can not build ROOT and got following error.What is “-Wno-long-double”?
============================================================================================
cc1: error: unrecognized command line option "-Wno-long-double"
Running build/unix/compiledata.sh
Making include/compiledata.h

make: bin/rmkdepend: No such file or directory
make: *** [cint/src/g__cfunc.o] Error 1

My arch. is “MacOSX 10.6.6 ,gcc4.2.1”.
Please give me advice.

Best Regard,

Kimiaki

Please try a more recent version of ROOT on your Mac OS X 10.6.6 machine.

Cheers, Fons.
