How to determine Python where Atlas is installed

I am currently installing a package scikit-learnfor Python on a computer without root access. Using Python 2.7 on Fedora 14.

pip is not installed, so I use easy_install:

easy_install --prefix=$HOME/.local -U scikit-learn

The installation process complains that BLAS is not installed. I tried to install scipy in the past and had problems finding and installing Atlas / BLAS. Since then I have verified that numpy has no problems with Atlas:

>>> import numpy as np
>>> np.__config__.show()
atlas_threads_info:
    libraries = ['lapack', 'ptf77blas', 'ptcblas', 'atlas']
    library_dirs = ['/usr/lib/atlas']
    language = f77
    include_dirs = ['/usr/include']

blas_opt_info:
    libraries = ['ptf77blas', 'ptcblas', 'atlas']
    library_dirs = ['/usr/lib/atlas']
    define_macros = [('ATLAS_INFO', '"\\"3.8.3\\""')]
    language = c
    include_dirs = ['/usr/include']

atlas_blas_threads_info:
    libraries = ['ptf77blas', 'ptcblas', 'atlas']
    library_dirs = ['/usr/lib/atlas']
    language = c
    include_dirs = ['/usr/include']

lapack_opt_info:
    libraries = ['lapack', 'ptf77blas', 'ptcblas', 'atlas']
    library_dirs = ['/usr/lib/atlas']
    define_macros = [('ATLAS_INFO', '"\\"3.8.3\\""')]
    language = f77
    include_dirs = ['/usr/include']

lapack_mkl_info:
  NOT AVAILABLE

blas_mkl_info:
  NOT AVAILABLE

mkl_info:
  NOT AVAILABLE

/usr/lib/atlas exists and contains .so files.

This was an error on which easy_install exists:

error: Setup script exited with error: Command "gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686 -mtune=atom -fasynchronous-unwind-tables -D_GNU_SOURCE -fPIC -fwrapv -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686 -mtune=atom -fasynchronous-unwind-tables -D_GNU_SOURCE -fPIC -fwrapv -fPIC -I/usr/lib/python2.7/site-packages/numpy/core/include -I/usr/lib/python2.7/site-packages/numpy/core/include -I/usr/include/python2.7 -c sklearn/__check_build/_check_build.c -o build/temp.linux-i686-2.7/sklearn/__check_build/_check_build.o" failed with exit status 1
/usr/lib/python2.7/site-packages/numpy/distutils/misc_util.py:248: RuntimeWarning: Parent module 'numpy.distutils' not found while handling absolute import
  from numpy.distutils import log

And warnings earlier in the installation:

/usr/lib/python2.7/site-packages/numpy/distutils/system_info.py:1392: UserWarning:
    Atlas (http://math-atlas.sourceforge.net/) libraries not found.
    Directories to search for the libraries can be specified in the
    numpy/distutils/site.cfg file (section [atlas]) or by setting
    the ATLAS environment variable.

Thus, the installation process does not seem to be able to find either numpy or Atlas. How can I tell where to find them?
