Well, the db interface with python appears to be working... so I may be 
able to do some low-level testing that way.   (I have to preload libelf 
for some reason.  I'll have to track that down.)

bash-2.05b# cat rpmtesting.py
#!/usr/bin/python

import rpm
import rpmdb

dbhandle = rpmdb._db.DB()
print dbhandle.open( 'mytestdatabase', rpmdb._db.DB_BTREE, 
rpmdb._db.DB_CREATE, 0664 )
print dbhandle.put( 'mykey', 'mydata' )
print dbhandle.get( 'mykey' )
print dbhandle.close()

print "Done with create... checking for data:"
dbhandle = rpmdb._db.DB()
print dbhandle.open( 'mytestdatabase' )
print dbhandle.get( 'mykey' )
print dbhandle.close()

bash-2.05b# ./rpmtesting
None
None
mydata
None
Done with create... checking for data:
None
None
None
bash-2.05b#

When the db is re-opened, there isn't any data there.  Not good.

bash-2.05b# db_verify mytestdatabase
bash-2.05b# db_dump mytestdatabase
VERSION=3
format=bytevalue
type=btree
HEADER=END
DATA=END
bash-2.05b# db_dump -r mytestdatabase
VERSION=3
format=bytevalue
type=btree
HEADER=END
DATA=END
bash-2.05b# strings mytestdatabase
bash-2.05b#

This looks like the data isn't making it to disk...  Perhaps I have 
something wrong in configure?  Or....?

Any ideas?
