[Matplotlib-users] Problems installing MPL on OS X 10.6 Snow Leopard with python2.7

Hi all,

I am trying to install matplotlib on a MacMini Intel Core 2 Duo with a clean
install of Mac OS X 10.6.  I am using python 2.7 that I built from source
using the homebrew package installer.  I also installed numpy 1.5.1 from
source, using the following environment variables:
export MACOSX_DEPLOYMENT_TARGET=10.6
export CFLAGS="-arch i386 -arch x86_64"
export FFLAGS="-m32 -m64"
export LDFLAGS="-Wall -undefined dynamic_lookup -bundle -arch i386 -arch
x86_64 -framework Accelerate"

I also used gfortran 4.2.3 precompiled that I downloaded from
http://r.research.att.com/tools/

NOTE: I previously performed this whole install process on a brand new
MacBook Air, and it worked without a problem.

I ran numpy.test() and got the following output:

In [4]: numpy.test()
Running unit tests for numpy
NumPy version 1.5.1
NumPy is installed in
/usr/local/Cellar/python/2.7.1/lib/python2.7/site-packages/numpy
Python version 2.7.1 (r271:86832, Dec 13 2010, 14:21:05) [GCC 4.2.1 (Apple
Inc. build 5664)]
nose version 0.11.4

[...snip...]

Ran 3006 tests in 18.696s

OK (KNOWNFAIL=4, SKIP=1)
Out[4]: <nose.result.TextTestResult run=3006 errors=0 failures=0>

Also, when I try to import numpy.core.multiarray, I get no errors.

Finally, I cloned the latest GitHub MPL and set make.osx to be the following
(note: changed pyversion, pngfamily, pngversion, deployment target, and the
FFLAGS variable):

# build mpl into a local install dir with
# PREFIX=/Users/jdhunter/dev make -f make.osx fetch deps mpl_install
MPLVERSION=1.0rc1
PYVERSION=2.7
PYTHON=python${PYVERSION}
ZLIBVERSION=1.2.3
PNGFAMILY=12
PNGVERSION=1.2.44
FREETYPEVERSION=2.3.11
MACOSX_DEPLOYMENT_TARGET=10.6
OSX_SDK_VER=10.6
ARCH_FLAGS="-arch i386 -arch x86_64"

## You shouldn't need to configure past this point

PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig"
CFLAGS="-arch i386 -arch x86_64 -I${PREFIX}/include
-I${PREFIX}/include/freetype2 -isysroot
/Developer/SDKs/MacOSX${OSX_SDK_VER}.sdk"
LDFLAGS="-arch i386 -arch x86_64 -L${PREFIX}/lib
-syslibroot,/Developer/SDKs/MacOSX${OSX_SDK_VER}.sdk"
FFLAGS="-arch i386 -arch x86_64"

The install seems to go fine.  I can import matplotlib.  But when I import
matplotlib.pyplot, I get the following:

In [2]: import matplotlib.pyplot

ImportError: numpy.core.multiarray failed to import


It is strange because when I import numpy.core.multiarray, I have no
problems.  It also raises a RuntimeError, yelling about an ABI
incompatibility.

Does anyone know how to solve this problem?  I was able to get this to work
on another computer..strange that it fails now.

Thanks!
