title: Building software collections metapackage fails under Fedora 20/21
body: <p>I am having some problems in building a software collections metapackage under fedora 20 or 21.  It works ok under RHEL7/RHEL6/Fedora19.  I get the same error if I just copy the example on the software collections website (<a href="https://www.softwarecollections.org/en/docs/guide/#sect-Creating_a_Meta_Package" rel="nofollow">https://www.softwarecollections.org/en/docs/guide/#sect-Creating_a_Meta_Package</a>) </p>
  
  <p>The error I get is (assuming my scl is named 'myscl')</p>
  
  <pre><code>error: File not found: /home/user/rpmbuild/BUILDROOT/myscl-1-1.fc21.x86_64/opt/rh/myscl/myscl
  </code></pre>
  
  <p>It looks like the software collection name is getting repeated for some reason.  </p>
  
  <p>As I say this works fine on RHEL7, where the scl-utils* packages are older.</p>
  
  <p>Any advice would be greatly appreciated.</p>
