The current Python wrapper for `httplib2` breaks when running e.g.
`./result/bin/calcurse-caldav` with the following error:
```
Traceback (most recent call last):
File "./result/bin/calcurse-caldav", line 6, in <module>
import httplib2
ModuleNotFoundError: No module named 'httplib2'
```
The easiest workaround is to use the `wrapPython` tool to properly patch
library path inside the script.
