dvb_usb symbols from media_build disagree on Linux 2.6.32-32

dvb_usb symbols from media_build disagree on Linux 2.6.32-32

[Jan Hoogenraad]

Trying to compile and install media_build on an Ubuntu Lucid computer
Linux 2.6.32-32-generic-pae #62-Ubuntu SMP Wed Apr 20 22:10:33 UTC 2011 
i686 GNU/Linux

I can compile, but cannot use dvb-usb. With the snapshot of june 11th, I 
was able to do this with no problem.
Can somebody help me ?

sudo modprobe dvb-usb
yields
FATAL: Error inserting dvb_usb 
(/lib/modules/2.6.32-32-generic-pae/kernel/drivers/media/dvb/dvb-usb/dvb-usb.ko):

Yes, I have had a similar problem with Ubuntu Natty 2.6.38-10

The solution is to rminstall using the old media_build before installing
the latest media_build. Otherwise, you will have to reinstall the latest
Ubuntu kernel.

For some reason an old dvb-usb(or dependants) module isn't being removed
with the latest media_build.
