Are you using smokegen from git as well?
This should definitely not happen. smokegen contains the line

lib.setFileName(app.applicationDirPath() + "/../lib" + LIB_SUFFIX + 
"/smokegen/generator_" + generator);

to load the generator plugin. Note that smokegen doesn't link against these, 
they're loaded dynamically. So if your smokegen is in /opt/kde4/bin/smokegen, 
it should load /opt/kde4/lib/smokegen/generator_smoke.so. If it doesn't, 
Solaris seems to be doing something strange.

I'll get a copy of OpenIndiana and try it in a VM, maybe I can track down the 
problem easier then. I can't promise anything before the weekend though.
