dbus: how to avoid conflicts when multiple macports installations are present?

[Mojca Miklavec]

Hi,

There might be an obvious answer, but: how do I resolve the conflict
between dbus from two macports installations trying to install the
same file?

The error is the same as reported in the following tickets (which have
all been closed as invalid):
- https://trac.macports.org/ticket/30107
- https://trac.macports.org/ticket/34359
- https://trac.macports.org/ticket/37278

I would say that dbus should be at least aware of the potential
problem, check in advance if the file exists and ask the user
something like "Did you install MacPorts to a different prefix or did
you delete an old MacPorts installation without uninstalling the ports
first?" And maybe refer to some place on the wiki.

Thank you,
    Mojca
