Installing *.qpk

Trying to install gtk files from the 3rd party repository on my qnx machine.
The files are *.qpk, and the installer won’t load them. I tried to rename
them to *.qpr, but that didn’t work either. My qnx box isn’t connected to
the net yet, so I downloaded them onto an XP box, and transferred them on a
floppy. The floppy is good, the installer sees and installs the qpr files
on it. Any ideas on installing a standalone package?
