RE: sfs compile problems

Hi,

well, i realized why i was having problems with the db->open.  its because
i had to download Berkeley DB 4.1.x.  couldn't find an older version
anywhere.  The new api has an extra parameter (second parameter of
type DB_TXN) which can be set to NULL for backward compatibility.

ran gdb. looks like its trying to do a "c_get" from the cursor and that's
a null function ptr.
