I don't think it should be necessary if you don't normalize the path in 
the outer fc-cat loop, because you have to treat the directory anyway 
before you can emit the cache, which should cause the proper directory 
to be added to fontDirs.  Clearly the present code is incorrect, and 
I'll look at it (since I'm now back in civilization), but I think that 
we can avoid the issues involved with your patch.

Also, if d->name and dir don't match, there's something wrong...
