[sqlite] Dealing with 2 versions of SQLite

[gohaku]

Hello everyone,
I just installed SQLite v3.0.0.
However, I still have v2.8.11 of the SQLite interpreter ( sqlite ) on 
my system.

I would like to know the differences between a SQLite v3 and v2.8 
installation,
aside from interpreters ( sqlite and sqlite3 )

Also, where are the sqlite libraries located and how can I verify its 
version number?

Thanks in advance.
