cqueues doesn't work on FreeBSD 13.1

[duncan-bayne]

I've used luarocks to install http, which in turn fetches cqueues as a dependency. However, when I run my Lua script:

lua54: error loading module '_cqueues' from file '/home/duncan/code/halp/lua-modules/lib/lua/5.4/_cqueues.so':
        /home/duncan/code/halp/lua-modules/lib/lua/5.4/_cqueues.so: Undefined symbol "inotify_init"
stack traceback:

        [C]: in function 'require'
        ...e/duncan/code/halp/lua-modules/share/lua/5.4/cqueues.lua:2: in function <...e/duncan/code/halp/lua-modules/share/lua/5.4/cqueues.lua:1>

This is probably related to FreeBSD not supporting inotify; it's a Linux kernel feature not supported by FreeBSD.

Versions of things:

• Lua 5.4.4
