in principle, probably yes, but it's a bit of a can of worms. We've had
quite some trouble in the past with subtle differences in compilers,
etc. Our conclusion so far was that the only safe option is to build
against the flavor of R that is going to be used at runtime.

(In fact, you can even select a different R installation using a
command-line switch, already, but that, too is only safe under certain
conditions.)

Either way, on the original subject, we've tracked down the issue to a
silly typo in the code that was trying to make sure the dbus session
bus is running. No os version issues involved, after all. The
observed difference was between machines where the session bus was
already running, and those where it was not...

Marko, we're going to release version 0.6.3, tomorrow, and of course it
would be nice, if the official portfile could get updated, soon. Now
we did not manage to prepare that in time (but what we have so far is
at [1]), and Meik is on his way to a conference. If you could help us,
here, that would be much appreciated. The changes needed:

- We moved from SF.net to KDE.org, thus
   homepage -> http://rkward.kde.org
   lists.sf.net:rkward-devel -> lists.kde.org:rkward-devel
   master_sites -> ?
   livecheck.url -> ? The release is going to be at
     http://download.kde.org/stable/rkward/0.6.3/src/rkward-0.6.3.tar.gz
     not, there, yet, but there are some files in
     http://download.kde.org/unstable/rkward/, already.
- If the portfile is based on the .tar.gz (I think it is, right?), we'll
  need a patch for that silly typo, above: [2]
- Not sure, if the pre-activate section is still needed.

What can I do to help with this, best?

Regards
Thomas
