Bugzilla Bug 55313

net-mail/vpopmail-5.4.0-r1 fails in ./configure if userpriv is set in the
features flag.  vpopmail requires root privs for ./configure, and emerge should
ignore the userpriv flag for this ebuild.

Reproducible: Always
Steps to Reproduce:
1. Set the "userpriv" in your /etc/make.conf's FEATURES flag.
2. emerge vpopmail

 * Massive important warning if you are upgrading to 5.2.1-r8 or older
 * The internal structure of the mail storage has changed for
 * consistancy with the rest of Gentoo! Please review and utilize the
 * script at /var/vpopmail/bin/vpopmail-Maildir-dotmaildir-fix.sh
 * to upgrade your system! (It can do conversions both ways).
 * You should be able to run it right away without any changes.

 * Use of vpopmail's tcp.smtp[.cdb] is also deprecated now, consider
 * using net-mail/relay-ctrl instead.

Expected Results:  
emerge should have been "smart" and ignored the userpriv features flag for this
ebuild.

Workaround:
Disable the userpriv features flag manually for this ebuild, and reset it after
vpopmail is installed.
