I'm attempting to compile a kivy app for android using the python3crystax recipe. When building only with recipes listed in python-for-android, it compiles fine, but whenever I attempt to add a pip dependency, it fails with this error:

```
[ERROR]:   Didn't find any valid dependency graphs.
[ERROR]:   This means that some of your requirements pull in conflicting dependencies.
[ERROR]:   Exiting.

```

When using the python2 recipe, however, it compiles fine. Does python3crystax support installing dependencies over pip?
