Hmm, I see the same.  I don’t know why this happens.  With LUA_CPATH and
LUA_PATH set as they are in the wrapper I can load the “ssl” module just
fine.

The error is reported in “core/certmanager.lua” in the function
“create_context”, which contains this line:

        if not ssl then return nil, "LuaSec (required for encryption) was not 
found"; end

“ssl” doesn’t appear to be defined anywhere.  At the top of the file
it’s just “local ssl = ssl;”.

LuaSec is found by “util/dependencies.lua” or else we would see a
complaint printed to stdout upon application start.

Archlinux users also reported problems with latest prosody and latest
luasec: https://bugs.archlinux.org/task/48480

This makes me think that this is not a problem with this package per se,
but with Prosody.
