Well I must add, after the "dpkg -i",
$ dpkg -l | grep rkward
iU  rkward           0.4.7-2         a KDE frontend to the R statistics language

and rkward does indeed start without any non-trivial warnings or
errors, inspite of the "iU" status. And seems to work!

Here is the (later) output of "dpkg-buildpackage -rfakeroot -nc" for
the svn code... The bash error is gone but the other errors remain.
And it leads to the earlier mentioned issue of dependency on R-2.4.9

I am using Kubuntu Feisty (debian based!), so I suspect (forgot to
look up last night and am back in the dept now) gcc is 4.1
