loading modules that depends on dylibs on Ubuntu

[Wesley Smith <wesley.hoke@...>]

Hi list,
I'm having some trouble getting a module I've made to load on Ubuntu
8.04.  the module links against a shared library itself, which I've
placed in /usr/local/lib.  I've set my ldconfig environment to pull
libs from there and it works when running an app from the command line
that links against libs in /usr/local/lib, but when I go to load my
Lua module, I get can't find library errors.  These errors are for
exactly the libraries in /usr/local/lib.  As soon as I move them to
/usr/lib, it works.

so, what gives?  Why would my setting of ldconfig work for app
binaries, but not for binary lua modules?

thanks,
wes
