Re: Getting Error: undefined symbol: sqlite3_enable_shared_cache

OK, I figured out how to get Trac to work.  Looking at the error "global 
name 'sqlite' is not defined", I thouch that it could be a scope thing 
(please remember I don't know Python).  The error originated in 
site-packages/trac/db/sqlite_backend.py which imports sqlite like this:


    try:
        import pysqlite2.dbapi2 as sqlite
        have_pysqlite = 2
    except ImportError:
        try:
            import sqlite3 as sqlite
            have_pysqlite = 2
        except ImportError:
            try:
                import sqlite
                have_pysqlite = 1
            except ImportError:
                have_pysqlite = 0


Figuring that somehow the try block put sqlite out of the global scope, 
I decided to add the import line above the try block:

    *import pysqlite2.dbapi2 as sqlite*
    try:
        import pysqlite2.dbapi2 as sqlite
        have_pysqlite = 2
    except ImportError:
        try:
            import sqlite3 as sqlite
            have_pysqlite = 2
        except ImportError:
            try:
                import sqlite
                have_pysqlite = 1
            except ImportError:
                have_pysqlite = 0

This seemed to fix it.  Was my reasoning correct?  Can you explain to me 
why this would have happened?

Thanks,
Jeremy
