When this issue arose up for www-client/opera because of upcoming Qt4 builds of (binary only) Opera, the qt team advised to only provide a qt3 USE flag and (thereby) make qt4 the default. So only if USE=qt3, then you get a Qt3 build of Opera[1]. Contrarily, net-print/hplip-3.9.4b appears to make Qt3 the default, while it could do entirely without IUSE=qt4, just like www-client/opera. Kind regards, jer [1] Technically speaking, you sometimes do get a Qt3 build in preview releases, but this shouldn't happen with stable releases of Opera.
