If you're under Linux you can do this

$ LD_PRELOAD=/usr/lib/libsqlite3.so lli output.s

This will preload the sqlite library so that the interpreter can find
the external functions.

On a completely different note please remember to do "reply-all" when
replying to emails so that llvmdev gets CC'ed so that everyone can
benefit from this discussion.

Hope that helps.
