I'm seeing this on luajit on El Capitan:

|| lua: error loading module 'stringy' from file '/Users/jdonaldson/env/lib/lua/5.1/stringy.so':

It works if I downgrade to 0.2-1 That was suggested by these related articles :
Kong/kong#213
Kong/kong#1736

I updated to a version 0.5-0 that attempts to explicitly include the fastsearch.h header. I built this a long time ago and haven't done much with lua and especially not lua rocks. If you could test and verify that v0.5-0 works, I'll try to get it into luarocks.org (I can't even remember how to do that). Otherwise, I'm open to any suggestions on how to fix.

Thanks for preparing a release. I'm hitting some env problems with my macos environment. A missing size_t implies I'm missing stddef.h, but that's not the case. I'm stuck here, any ideas?

I pushed a new release: 0.5-1. could you try that? thanks.

Cool, looks like some progress. I can build and install successfully. That warning on fastsearch is there, but it's probably not worth messing with.

I can't load the library in lua though:
