rpm -e does not remove the package...?

[Evert <evert poboxes info>]

Hi all!

When I type:
   rpm -e gcc-gnat
I get the following output:
   /usr/share/info/dir: could not read (No such file or directory) and could not create (No such file or directory)
   /usr/share/info/dir: could not read (No such file or directory) and could not create (No such file or directory)
   error: %preun(gcc-gnat-3.3.2-1) scriptlet failed, exit status 1

And the package does NOT get (completely) removed...

How do I remove this package anyway?

Regards,
  Evert
