I am trying to build spidermonkey in my msys2 environment and follwed the steps layed out by mozilla.
This worked until the configure script. The first problem was, that the configure script just assumed "cl" as the compiler for windows, which was fixed quite simple.
The next problem is with python.

As i do not know python nor it's libraries, i thought i asked for some advice as to how to fix this.
You can't use msys python for Mozilla builds yet. It is something I hope to fix soon. Until then you should use the official Python 2.7.10 instead.
