New description:

 I've been trying to install py27-astropy for days now but 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 this log file tells me (eventually):

 {{{

 }}}

 from which I gather that the compiler clang is necessary. I did not appear
 to have this compiler, so I installed it via macports (clang-3.4), but
 still get the same error trying to install astropy. I cannot find any info
 about how to tell macports to use a different compiler here.
