Anyone build successfully？

Trying build the server, I got this:

```
---- inj ----
| Traceback (most recent call last):
|   File "/Volumes/AndroidSrcCode/adbi/ADBI/idk/inj", line 16, in <module>
|     from elftools.elf.elffile import ELFFile
| ImportError: No module named elftools.elf.elffile
```

But, can't find elftools.zip in the project.
