As part of exp-run in bug 223922 this port was found to break on Boost update. If the issue won't disappear on its own by Boost release I plan to mark the port as BROKEN. Can you check with upstream maintainer or help with a fix?

Well, the maintainer won't support 3.3.7 anymore since the latest release in 3.x branch is 3.3.9 which was released around two weeks ago. Earlier, I made a patch to upgrade to 3.3.8 and it never hit the ports due to a bug in Poudriere builds (issue #222920). I'll try to make a new patch for 3.3.9 and see if it resolves the issue with Poudriere and submit it here. I guess if it won't work then I have to patch it myself.
When will boost-1.66.0 hit the ports?
Sorry, ignore the last link. I pasted the wrong one.

Once Boost 1.66 is released another exp-run maybe required. After that it'd depend on how much bustage remains and whether I have time to reduce it before 2018Q1 branches. So, probably at the start of January.
 See calendar - http://www.boost.org/development/index.html
OK, thanks for the info. I'll try to fix it and report back in time.
It appears that the upcoming versions wt-3.3.9 and wt-4.0.2 are free of this boost failure.
portmgr@ set EXPIRATION_DATE in ports 474787. It's unlikely to result in removal due to pending update.
Yes, thanks, I will commit it soon.
