[AstroPy] Newbie installation problems

[COLIN NAVIN]

Hi

I am trying to install some packages as part of the installation process
outlined in Installing Scientific Python on the Python4Astronomers site.

I chose the EDP Academic distribution for Mac OSX 10.8 and installed the
core Python okay including gcc and gfortran.

When I come to the section about installing and checking additional
packages, some install fine (asciitable, pyfits and pyparsing). Others
(pywcs, atpy, aplpy, and pyregion) give installation errors. For example

pip install --upgrade pywcs



stops with an error message

wcslib/C/wcserr.c:140: internal compiler error: Segmentation fault: 11

Please submit a full bug report,

with preprocessed source if appropriate.

See <URL:http://developer.apple.com/bugreporter> for instructions.

error: command 'gcc' failed with exit status 1



Any help appreciated.

thanks

Colin
