An error report already exists for this . The problem has not yet been fixed, but someone uploaded a patch that you can try:

The reason is the POSIX module, which returns a lot of “-1” values, where Number :: Format-> new () expects missing hash keys ... I was able to successfully test and install using the attached patch as a workaround. But it might be wiser to fix this problem in the POSIX module.
