Currently building python on linux only looks for sqlite include paths in a hardcoded set of system paths, but if the user specifies -I/-L options during compilation, python setup.py looks there for sqlite3 as well, but only on OS X. This is problem for people who want to build python against a local version of sqlite3, and it is also inconsistent with the OS X behavior. Also the comments say that it should work on any unix-y OS!
