Thanks for this New Feature Doug! It's almost exactly what I have been 
meaning to ask for. A couple of enhancement requests...

1. Could it please use DISTDIR if defined in /etc/make.conf
2. Could it please have an option to clean distfiles for ALL (rather 
than just installed) ports (cf. 'portsclean -D' and 'portsclean -DD')

rwsrv05# portmaster -h
portmaster version 1.14

rwsrv05# portmaster --clean-distfiles-all
===>>> Gathering distinfo list for installed ports
===>>> Checking for stale distfiles
find: /usr/ports/distfiles: No such file or directory

rwsrv05# portsclean -D

Thanks again.
