Oh great, right after my last post I realized the solution to the issue: type sqlite3, not just sqlite at the command prompt. Many of us have an older version (2.8.17 for me in my Tiger installation) in our command path. sqlite3 has the import command, version 2 does not.
Here is the output of .help from sqlite, and below the output from sqlite3:
