The better way to fix it is to do a patch like this one:
The problem with those dib drivers is that there's no way to latter
remove them with rmmod. Using the above techinique, not only ranconfig
compilation will work, but it will also allow module remove and having
drivers with some frontends disabled.
The drawback is that it is not a very trivial patch, so I did the
changes only for devices that I have (all based on dib0700).
Unfortunately, I don't have any device currently based on dib3000.
I could work on such patchset, but someone would need to test it ;)
