installation problems in mac machine

Hi,

My operation system is Mac OS X 10.6.2. I unzip the petsc under 
/usr/local/petsc-3.0.0-p10.
I use the following to configure petsc.
-------
 sudo ./config/configure.py --CFLAGS=-O3 --FFLAGS=-O3 
--with-mpi-dir=/usr/local/mpich2-1.2.1 --with-fortran --with-shared=0 
--with-fc=gfortran
-------

And I run the following commands:
----
export PETS_ARCH=darwin10.2.0-c-debug;
PETSC_DIR=/usr/local/petsc-3.0.0-p10; export PETSC_DIR
----

When I run " sudo make all", it gives some errors:
-----
makefile:15: /conf/base: No such file or directory
makefile:16: /conf/test: No such file or directory
make: *** No rule to make target `/conf/test'.  Stop.
-----

It seems it cannot find the PETSC_DIR. (I use x11. "echo $SHELL" gets 
"/bin/bash")
Do I need to add "PETSC_DIR = /usr/local/petsc-3.0.0-p10" in the makefile 
file? Thanks.

Bests,
