Repairing a bad "erase"

I had just installed a package and realized that I need to do some
customization and therefore would need to build from source.. I ran
the rpm -ev on the package and it proceeded to work through the
uninstall.... but it hung at what appeared to be near the end.. I left
it alone for about an hour and it still did not return to the prompt..
I finally had to restart the system because I could not get a cursor in
any terminal.. (strange)

First, any idea what happened, and how could I have recovered more
gracefully..

Second..

rpm -qa | grep -i name

...still indicates that this package is installed.. I tried to
re-install using --replacepkg and it would not.. (listed dependencies)
I also tried --force.. same messages.. I had hoped to reinstall it then
do another uninstall.. no joy..

Any suggestion as to how I can clean up this "partially"
uninstalled package.. and remove it.. (it BTW is not seeming to cause
problems as far as I can see, but I hate to leave loose ends like this..)

Thanks for any suggestions..

John...
