SQLite project pay high attention to compatibility. AFAIK, all changes  
except
first digit are upward compatible - you can take bindings for 3.5.0 and  
link
wih 3.7.6 - all will work as expected, You just will not see new API.

P.S. I updated bindings version to 3.7.6.2 and fixed one bug (see github).
