Hang in there. It would be nice to get this going, and document it. It is, as
so many things, frightfully tedious in Windows but I think it can be done.

That is easier and quicker than to rebuild Qt...  But no, you can trust the
binary from CRAN with respect to the Rtools toolchain.

But you do have to have a compatible Qt.  And when I did this, I think they
did not yet offer the "all-in" option but only source (Qt 4.1 or 4.2 ?). So I
had to anyway.

It may of course also work with the Qt binary you got.  Sometimes it is just
link order etc pp.  But hard to tell.

Good luck, and keep trying.

Dirk
