db problems in 1.0.2

I came across current last week, happily set up on RedHat 7.2 for my own
munged distribution.  Worked perfectly :)

Another week and another job later ...

Have downloaded current on a RedHat 6.2 box + updates which is the
distro for my new employers.

Set up current as before, cadmin happy generating databases.

However when I initialise current it dies.  I think it is a db issue, or
maybe it just doesn't work on RedHat 6.2 as the server ...

I'm thinking maybe rebuild python from src.rpm against the libc and db3
libraries but it seems dynamically linked, any ideas.  Lots of data
follows...

[root@fred lib-dynload]# ldd bsddbmodule.so
        libdb.so.3 => /lib/libdb.so.3 (0x40009000)
        libdb.so.2 => /lib/libdb.so.2 (0x40043000)
        libc.so.6 => /lib/libc.so.6 (0x40051000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)


I added an extra logException() line in to locate what was going on:

I played about and it's the bsddb.btopen returning this, I get it when I
try and open the files just using the module.

Which is where the index gets opened up.
