[ILUG] RPM trickery

[Stephen Shirley]

Mornin',
	I have a user account on a machine which I want
to install an rpm on. I do not have root access, but I
want to try install the rpm into my own directory. I have
already created an rpm db in my home dir using
rpm --initdb --dbpath=/home/dimaond/myrpm/
But when I try to install the package using
rpm -Uvh --dbpath=/home/diamond/myrpm glimmer.rpm
I get 
glimmer                     unpacking of archive failed on file
/usr/bin/glimmer: cpio: open failed - Permission denied
Any ideas?
