installation on Mac OS X Yosemite

Hi,

I don't know if it is a problem with the last version of Mac OS X, but I don't manage to build petsc4py

I have succesfully installed mpi4py and upgraded numpy. I built PETSc recently with version 3.5

Then I ran

pip install petsc petsc4py

but got the message

Downloading/unpacking petsc
  Could not find any downloads that satisfy the requirement petsc
  Some externally hosted files were ignored (use --allow-external petsc to allow).
Cleaning up...
No distributions at all found for petsc
Storing debug log for failure in /Users/timotheenicolas/.pip/pip.log

Just in case, I attached the log file.

So I tried just

pip install petsc4py

It said it compiled succesfully, but actually complained about not finding the PETSC_DIR, although it is exported to /Users/timotheenicolas/PETSC/petsc-3.5.3

Then when I try to use it in python I get messages like

ImportError: invalid 'PETSC_ARCH': 'arch-darwin-c-debug'

So after googling around I found other people had similar issue and a possible work around :

https://code.google.com/p/petsc4py/issues/detail?id=24 where it is said to build python with

ARCHFLAGS='-arch x86_64' PETSC_DIR=/Users/buildbot/data/opt/petsc-3.3-p3 python setup.py build

So I git-cloned the repositery version and implemented the command after replacing PETSC_DIR my its value on my machine, but I got the error message

error: /Users/timotheenicolas/PETSC/petsc-3.5.3/lib/petsc/conf/petscvariables: No such file or directory

Which seems to indicate that petsc does not comply with the structure of my PETSc version 3.5 build.

How could I overcome this issue ?

Best
