I encountered the same problem a while ago. Rosegarden does not look in
lib64 for DSSI and LADSPA plugins. An easy workaround is to place
symlinks in /usr/lib.
Assuming that /usr/lib64/dssi exists, from within /usr/lib (create the
directory if it doesn't exist) type the following:
ln -s /usr/lib64/dssi dssi
In order to use LADSPA plugins, the following will work:
ln -s /usr/lib64/ladspa ladspa
A better fix, of course, is to patch src/sound/DSSIPluginFactory.cpp and
src/sound/LADSPAPluginFactory.cpp with additional path information.
I've attached a patch I've been using.
