pkg-installer without Photon

Hello, I’m trying to figure out how to down-load a package (patch B) from
QNX on a QNX RTP system that does NOT have Photon installed but without
I have tried to give all needed command line options to pkg-installer but it
always tries to find the Photon server (or something).

Is it possible at all to do this?

Best regards, Mats P
