For the record: these days you do not need any extra tools unless the
package contains code that needs compilation, and in the latter case
we provide the win-builder service.
However, the message indicates no file grt/Meta/package.rds, which
would be there if the package was copied from Linux. So we need to
know exactly what was done.
