error: can't unlink opt-RPMDELETE: directory

[Andrew Chapman <a91anch atcc necsys com>]

I have build an rpm file on my machine. I can install successfully
on my machine, but when a user tries to install on their machine
they get the message

error: can't unlink opt-RPMDELETE: directory
error: can't rename opt to opt-RPMDELETE:  directory
error: unpacking of archive failed on file opt: cpio: unlink failed - directory

I have read the archive file for this list rpm-list@redhat.com,
and I see people reporting a similar error message, but no
responses with an explanation.

This may be an error due to bad permission on files, or some
other non-rpm factor, that occurs when installing a rpm file.
Is there some way to avoid this error?

Below are more details.

Thank you,
Andrew

Red Hat Linux release 7.1 for IA-64 is installed.

> uname -a
Linux neptune5 2.4.3-12smp #1 SMP Fri Jun 8 13:06:07 EDT 2001 ia64 unknown
> rpm --version
RPM version 4.0.2

I have told the user to update to RPM version 4.0.3

The user trying to install was root

The user tried using the rpm flag "-i --force --nodeps", and still
gets the error message.
