It's not .so versioning, it's plugin versioning. It apparently isn't
working. We should fix it.

Now, once 0.4.0 comes out, the minor will have changed. Plugins only
have major and minor coded into them. The check to load plugins is 

  if (major != GST_VERSION_MAJOR || minor != GST_VERSION_MINOR) 
    return FALSE;

so things should be better in theory when we do the actual installation.
Maybe you can give this a try.

The other thing you might want to think about would be not running
-register after every plugin package. Given that user registries exist,
and that if the registry is out of date -register will effectively be
run automatically the next time you run a gst app, I see no need anymore
for gst-register, in most cases.
