title: rpmbuild command won't find the build directory
body: <p>I am trying to install some config files using an rpm package and am having trouble with the final build step. I have tried using a lot of different variable combinations but I keep getting file not found errors. It appears to be a problem with where rpmbuild is unpacking (or not unpacking) files and where it anticipates those files. Right now I have a spec file that looks like this:</p>
  
  <pre><code>Summary: My Package
  Name: my-package
  Version: 1.1
  Release: Public
  Group: Applications/System
  License: Public
  Requires: collectd
  Source: sources.tar.gz 
  
  %prep
  %setup
  
  %install
  mkdir -p %{buildroot}/etc/collectd/
  mkdir -p %{buildroot}/etc/collectd/collectd.conf.d/
  mkdir -p %{buildroot}/usr/bin/
  
  
  # list files owned by the package here
  %files
  %defattr(-,root,root)
  %config /etc/collectd/collectd.conf.custom
  %config /etc/collectd/collectd.d/http.conf
  %config /etc/collectd/collectd.d/csv.conf
  /usr/local/bin/myfile.py
  /usr/local/bin/my-package
  
  %post
  ln -sf /etc/collectd.conf.custom /etc/collectd.conf
  </code></pre>
  
  <p>I currently get output which looks like this:</p>
  
  <pre><code>Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.m5Qvz9
  + umask 022
  + cd ./BUILD
  + LANG=C

  /var/tmp/rpm-tmp.m5Qvz9: line 31: cd: /BUILD: No such file or directory

  RPM build errors:

  <p>I'm not sure why it is trying to <code>cd</code> into the <code>/BUILD</code> directory twice. </p>
  
  <p>If I leave out the <code>%setup</code> line I get the following output:</p>

  <p>Which I would expect after remove <code>%setup</code> as it no longer unpacks the source. Any help appreciated.</p>
