[AstroPy] astropy 1.1.2 RHEL6 (python 2.6.6) test_imports.py : ImportError: cannot import name _erfa

Wed Aug 24 02:16:29 EDT 2016

Hi,

Does anyone know if this failure can be safely ignored ?

astropy.test(package='tests')  fails importing _erfa in test_imports.py
but
astropy.test(package='_erfa') is successful (5 passed)

Thanks
