Thanks, I added it and this step passed and now I don't get the previous error 
in building. 

Now I faced with another issue:
```
...
   Compiling serde_bytes v0.11.5
   Compiling rmp-serde v0.14.3
   Compiling sodiumoxide v0.2.6
   Compiling reqwest v0.10.4
   Compiling etebase v0.1.0
   Compiling etebase-python v0.30.0 
(/tmp/guix-build-python-etebase-py-0.30.0.drv-0/etebase-0.30.0)
error: unterminated double quote string
  --> src/lib.rs:63:44
   |
63 | include!(concat!(env!("OUT_DIR"), "/glue.rs"));
   |                                            ^^^^^

error: aborting due to previous error

error: could not compile `etebase-python`.
```

This error is related to this line: 
https://github.com/etesync/etebase-py/blob/64bce73fe2a9a6c82923cd3cedc9210b874f5c01/src/lib.rs#L62

I don't know what's this. And what should I do? Do you have any idea?
