macports destroot.umask not recursively applied

[tcwan (TC Wan)]

This was working fine in Sierra (10.12), and as far as I can tell, the initial release of High Sierra 10.13, but it no longer works after apply the High Sierra 10.13.1 root security patch.

I'm trying to build a user port which installs files under /opt/local/share/, but the default owner and umask no longer allows the install to write to the directories.

Invoking destroot.umask 002 does not solve the problem as it does not apply the mask to all subdirectories.

ll /opt/local/var/macports/build/___DELETED___/rftg/work/destroot/

drwxr-xr-x  2 root      wheel   68  5 Dec 10:53 usr/

drwxr-xr-x  12 root  admin  408  5 Dec 10:53 local/

I expect that destroot.umask to be recursively applied to all folders under /opt.
