title: Trouble installing scipy in virtualenv on a amazon ec2 linux micro instance
body: <p>I have successfully installed <code>scipy</code> in the default python compiler on an amazon ec2 micro instance (Ubuntu 13.04). However i am not able to install <code>scipy</code> in a virtualenv.</p>
  
  <p><code>pip install scipy</code> ends with this error</p>
  
  <pre><code>scipy/sparse/sparsetools/csr_wrap.cxx: In function ‘void init_csr()’:
  
  scipy/sparse/sparsetools/csr_wrap.cxx:73303:21: warning: variable ‘md’ set but not used [-Wunused-but-set-variable]
