Currently there is no dolphin package without ray. Though, i think, it should be there. Disabling ray widgets option is there, but we have to still edit the code to remove completely. Moreover, during installation of dolphin, complete ray folder should be there, or it won't be installed. After install you have to disable and remove the code from several sections like action block of profile page, search page...and few others...i can help u iff i get sufficient time.
