Strange indeed. As I mentioned, on one of my machines I had to try
installation a second time. In this case, I think the problem was that the
installation took more than 50% of the memory, but the machine was busy
with differnt things, so it failed. But it resulted in an error during the
installation, as it should!
Did you delete the copy of the package in spkg/optional before
reinstallation? Then I could imagine that the download for the first
installation was corrupted. Anyway, good that it works now.
Best regards,
Simon
