title: two versions of numpy
body: <p>My department has version &lt; 1.4 version numpy isntalled in /usr/lib/somewhere/numpy. Since I don't have the permission to replace it with a new version. I installed numpy 1.5 in my home directory. However, later when I install scipy, it complained that the version in /usr/lib/somewhere/numpy has version &lt; 1.4. How can I solve this problem?</p>
