Thanks for the suggestion Robby but no luck, I'm afraid.

DrRacket gives the error below. Although it then claims to complete the
installation, the server button doesn't appear even after a restart.

From the error message it seems that gnu-unzip expects the first two bytes
of the file to be #o037 and #o213. Looking at the .plt file, I can see that
they are indeed those values.

Any idea?
