1. www/pserv installs pserv.conf
2. user edits it to his needs
3. user deletes pserv with intention to install a new version.
pserv.conf is not deleted, because MD5 checksum is not the same
4. user installs the new version of www/pserv and pserv.conf is
overwritten, loosing user's valuable changes
Fix: Simply install pserv.conf as pserv.conf.sample
