Good to know.

FYI, I did use my kludge and created symlinks.  That seems to work okay for now.  I will try the patch as well (after removing the links).

It would be nice to be able to specify a locale in the configuration.  That way you can save 1 MB of space in your ramdisk (and on a machine without a lot of memory that is really nice). :)

Thanks, Detlev, for all your help!
