dev/ammo suggested:
sed 's#$PREFIX/lib/kde3#$PREFIX/lib/trinity#g'
which I think will work, but I can't figure out how to apply it to
configure. We are getting close. Please add thoughts and I'll try
again at lunch.
Actually it won't work because configure doesn't contain
the entire
string $PREFIX/lib/kde3.
IIRC the right sed is
's#kde3/plugins#trinity/plugins#g'.
