ports/devel/bin86 won't build with umask 027, but it will with umask
022. Ports should build with umask settings no less safe than 022, not
only 022. (They shouldn't warn about it, either.)
The "make" error message was:
install -c -s -o root -g wheel -m 555 `find /usr/ports/devel/bin86/work/bin86-0.16.0 -type f -perm 755 |grep -v encap` /usr/local/bin

*** Error code 64
I did "umask 027; portupgrade bin86; umask 022; portupgrade bin86".
