Fair enough.

There is once again no useful information here.

Print lv2_path and see what it is.  lilv_world_load_path() is your point
of interest, everything after (i.e. here) is after all the plugins are
discovered and irrelevant.  Stepping through lilv_world_load_path() will
explicitly show you exactly what directories are being searched.  It
will call lilv_world_load_directory() for each directory in the path.

It seems almost certain that your LV2 path is simply incorrect.  If not,
and lilv_world_load_directory() is indeed being called for actual
directories that contain LV2 plugins, then... well, we'll deal with that
if it's the case.  I suspect it's not.
