msf3 on osx

hi

i seem to be having an issue using the autopwn functionality in msf3  
on osx.

a db_nmap of a single host scanning on a single port seems to work  
fine, but when I do a db_hosts or db_services, it seems to error;

msf > load db_sqlite3
[*] Successfully loaded plugin: db_sqlite3
msf > db_create metasploit
msf > db_nmap -p 445 127.0.0.1

Starting Nmap 4.20 ( http://insecure.org ) at 2007-05-20 15:37 EST
Interesting ports on localhost (127.0.0.1):

If I try and db_nmap a subnet, it gives the error straight away

any ideas?
