It's a problem within the Fink distribution, not a problem with your
install as such.  In principle with sufficient man-hours the
dependencies could be cleaned up to get rid of such issues.

I believe that the error handler sends the name of the potential
package(s) which couldn't be installed to the very outermost layer where
fink interacts with the user, and the build module is done at that
point.  I.e. it "knows" what commands to run at a point where it's too
late to run them itself.

Since fink is open source, feel free to test out submit a patch to fink
to get it to auto-run-and-restart after such a dependency engine failure.
