Problem installing "module-init-tools"

["Don Jackson (AE5K)" <don1103@azark.com>]

Using either aptitude or apt-get, I receive the following message during 
install:

Unpacking module-init-tools 
(from .../module-init-tools_3.1-pre5-1_i386.deb) ...
md5sum: MD5 check failed for '/etc/modprobe.conf'
dpkg: error 
processing /var/cache/apt/archives/module-init-tools_3.1-pre5-1_i386.deb 
(--unpack):
 subprocess pre-installation script returned error exit status 1
Errors were encountered while processing:
 /var/cache/apt/archives/module-init-tools_3.1-pre5-1_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

Can someone tell me what this means and what I can do about it?  Or a pointer 
to where I might find further info?

Using: "testing"

At one point, deleted the "module-init-tools_3.1-pre5-1_i386.deb" file and did 
the apt-get again to download a new copy to see if that made a difference.  
It did not.

Thanks,
Don
