title: OSX Mavericks ATLAS install failure from source AND Macports
body: <p>I'm trying to install ATLAS (because I need LAPACK/BLAS) on Mavericks from source, since installation fails via Macports (possibly for the same reason?). The compiler can't be located despite numerous attempts to set it:</p>
  
  <pre><code>sudo ../configure -b 64 --prefix=/usr/local/atlas --with-netlib-lapack-tarfile=../../lapack-3.4.2.tgz -C alg /opt/local/bin/gcc-mp-4.7 -C if /opt/local/bin/gfortran-mp-4.7 --shared
  </code></pre>
  
  <p>The salient error is:</p>
  
  <pre><code>Unable to find usable compiler for ICC; abortingMake sure compilers are in your path, and specify good compilers to configure
  (see INSTALL.txt or 'configure --help' for details)make[1]: *** [atlas_run] Error 1
  </code></pre>
  
  <p>The Macports error message is:</p>
  
  <pre><code>---&gt;  Fetching distfiles for atlas
  ---&gt;  Verifying checksums for atlas
  ---&gt;  Extracting atlas
