Error when trying to install a new module

[Justin R. <ju...@ws...>]

	Hi all.. I'm trying to install a module and I'm getting the following 
output to my console:

[root@wsiwww webmin]# tar: ./portalplanet/module.info: Not found in archive
tar: Error exit delayed from previous errors

Does this have something to do with permissions somewhere? I'm attaching 
the module to this e-mail.. I'm trying to install the template tarball from 
http://www.niemueller.de/webmin/writers-help/download/module-template-0.79.1.tar.gz.. 
Trying to install it from a local file doesn't work either. I'm running the 
RPM version of webmin on Red Hat 6.1.

Thanks in advance,
Justin
