[Rd] problems with tcltk in R 2.0.1 (PR#7698)

[Prof Brian Ripley]

What do you think the bug is here?

The error message is saying there is an error in your code or code it 
calls, and without a traceback() we cannot tell where (see the comment 
below about a corrupt archive).

That something ran in 1.9.1 does not mean it is correct, and this is 
quite likely to be a previously undetected overwriting of an object in a 
package, perhaps by using <<-.

and that appears to be corrupt:

gannet% wget ftp://ftp.imr.no/vidarh/diva.zip
gannet% unzip -l diva
Archive:  diva.zip
warning [diva.zip]:  2735 extra bytes at beginning or within zipfile
   (attempting to process anyway)
error [diva.zip]:  start of central directory not found;
   zipfile corrupt.
   (please check that you have transferred or created the zipfile in the
   appropriate BINARY mode and that you have compiled UnZip properly)

(I've tried other routes to the same effect, and I am using binary mode.)
