Thanks for the detailed information, I'll add some commands
that I found useful while troubleshooting my own migration:
(which turned out to be failed because RPM4 hadn't been able
to detect the sqlite3_open function in the sqlite library...)

# dump a Berkeley-DB database as text
/opt/local/lib/rpm/rpmdb_dump /opt/local/var/lib/Packages

# dump a SQLite database as text
echo .dump | sqlite3 /opt/local/var/lib/Packages

Where /opt/local is of course replaced with your RPM prefix,
values above are from the default "rpm" port for MacPorts.
(the default muggler version of magic(5) for Mac OS X will
identify the SQLite databases as something dull like "data")
