PIP使用錯誤的體系結構

Question

在一個乾淨的，空的virtualenv做一個pip install scipy上odroid XU4安裝SciPy的（Python 2.7版，Ubuntu的15.04）

UNAME -a

Linux odroid 3.10.82-57 #1 SMP PREEMPT Wed Oct 7 13:19:01 BRT 2015 armv7l armv7l armv7l GNU/Linux

所以很顯然，點子沒有正確地拿起它的手臂。什麼是正確的方式來設置？

我注意到，arm7l（由uname列出）未列出在上面的錯誤跟蹤一個選項，但嘗試也無妨如下：

ARCHFLAGS='-arch arm7l' pip install scipy 

但完全相同的輸出。

我知道我可以apt-get install python-scipy，但我寧願通過pip來做，所以我可以使用最新版本並完全控制我的環境（調試ubuntu包裝的scipy掛在某些可在x64上正常運行的功能的問題）

編輯：嘗試直接從源編譯instructions here，但仍然是同樣的問題，gfortran沒有撿起正確的拱門。

通過安裝numpy的1.9.2
