umm, why not? you couldn't have a pySide wheel???just saying that the anaconda index literally has packages for "qt" itself, the c++ library.and it's pyside packages require that.
my understanding is that you could build a pyside wheel that was statically linked to qt.
as to whether a wheel could just package "qt". that's what I don't know, and if it could, the wheel spec doesn't cover that use case.
