I am (in principle for this project) using what I get from LuaRocks.

$ luarocks show lua-curl

Lua-cURL 0.3.6-1 - Lua binding to libcurl

License:     MIT/X11
Homepage:     https://github.com/Lua-cURL
Installed in:     /usr/local

Modules:
    cURL (/usr/local/share/lua/5.3/cURL.lua)
    cURL.impl.cURL (/usr/local/share/lua/5.3/cURL/impl/cURL.lua)
    cURL.safe (/usr/local/share/lua/5.3/cURL/safe.lua)
    cURL.utils (/usr/local/share/lua/5.3/cURL/utils.lua)
    lcurl (/usr/local/lib/lua/5.3/lcurl.so)

I have verified that the problem is present also if I require 'lcurl'
rather than 'cURL'.

My system is Ubuntu 16.04.2 LTS .
