Sorry for the long delay. I uploaded 1.16.1-2 yesterday which downgrades
http-lua to v0.0.13, the last working version, to unblock the perl
transition.

Copying from the http-lua's README (master, not yet released v0.0.16):

So I am working on a patch that skips building the module for non luajit
archs.
