 I've been trying to install py27-astropy for days now, to no avail,
 despite frantic googling.
 I get the following error:

 {{{
 Error: org.macports.build for port py27-astropy returned: command
 execution failed
 Please see the log file for port py27-astropy for details:
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports
 .org_release_tarballs_ports_python_py-astropy/py27-astropy/main.log
 }}}

 Checking the log file tells me (eventually):

 {{{

 :info:build                     You can do this, for example, by running:
 :info:build
 :info:build                         CC=clang python setup.py <command>

 :info:build                     where <command> is the command you ran.
 :info:build

 :info:build Exit code: 1
 :error:build org.macports.build for port py27-astropy returned: command
 execution failed
 }}}

 from which I gather I need the compiler clang. I did not appear to have
 this, so I installed it via macports and now have "clang-3.4
 @3.4.2_9+analyzer+arm_runtime (active)" but the error persists. So how do
 I tell macports to use a different compiler in this case?
