Unable to get the module to work

First I tried to Install the stable release of this module but I was unable to configure the refresh token for the module.

I referred this which says the dev release works.

I configured the dev release of the module successfully.

Now when I go to http://localhost/droogle page it does not load the page and gives a 500 Error.

It gives the following message on other pages :

Warning: require_once(Google/Service/Drive.php): failed to open stream: No such file or directory in droogle_gdrive_connect() (line 245 of /xxxyyy/sites/all/modules/Droogle/droogle.module).

I checked the file Google/Service/Drive.php has been moved to a different repository and is not available in the said location see here

I am using the latest library from google. here

I think the issue is the drive.php is not present in the said location.

Can anyone advice/help me get the module to work please or say me what I am missing?
