Problem in running Deckard for C project

Hi and thanks for the tool! 
I set up a config file to test my C project, following the one reported as sample in `scripts/clonedect`, but I obtain this error after running `./deckard.sh`:

```bash
==== Configuration checking...Error: missing file ~/Deckard-rel2.0solidity/scripts/clonedetect/src/main/cvecgen. Check your config
```
any suggestion?
Thanks in advance
