>Description:
When using nscd as lookup service, during deinstallation of port the cups-user and group get properly removed from the backend.
However, during reinstall, they get reported still valid from the nscd-cache, therefore breaking the cups-user creation part in the Makefile.
>How-To-Repeat:
Have nss make use of nscd, oviously

cd /usr/ports/devel/cups-base
make deinstall reinstall (clean)
>Fix:
expire the cache before asking for user id
