Yes, I got the same result.

This was caused by the v1.222 of 'include/Makefile.in'. And for tentative
solution, add two more lines which are deleted in this version. Since
I have no idea why we have both InetAddress and VMInetAddress classes,
and permanent solution should be advised by someone else.
