package problems

I’ve been attempting to install some packages onto a QNX RTP (6.1) server.
But, for whatever reason, the shared objects don’t get put into the
/usr/lib/ path…although it looks like they are installed in the right
place under /pkgs path.
Also, I am unable to create any files under /usr/bin … even the
executables don’t get installed into this path.
NOTE: I’m trying all this as root.
Please advise.
