I would advise against doing this. The installed sample files would
change depending on the user that ran the port command. The contents of
all files installed by a port should be reflected by the canonical
identifier of name/version/revision/epoch/variants.
Also this would not help if the user installs the port with a binary
archive from one of our buildbots, they would always get a pre-defined
username.
Wouldn't it make more sense to create a dedicated user to run the
buildbot daemon? See add_users in portfile(7) and grep for examples in
the ports tree. If you use some working directory in ${prefix}/var/ it
could even be used out of the box without further configuration.
