Compiler error trying to install Astropy

[shj.wallstrom@…]

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 Compiler specified by CC environment variable
:info:build                     (/usr/bin/llvm-gcc-4.2:i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on App$

:info:build                     You can do this, for example, by running:

:info:build
:info:build                     where <command> is the command you ran.
:info:build
:info:build Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org$
: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?
