First off I'm running:

I'm trying to preload a library into an application I'm debugging remotely, but seem to be unable to influence the 
environment on the target. Something as simple as LD_PRELOAD=foo.so on the target would be useful.

Right now I'm using the gdb command-line, but if there is a way to do this from Momentics that's fine too. 

After connecting to the target via:
(gdb) target qnx x.x.x.x:####

All of the following commands operate in the context of the host machine:
(gdb) set environment LD_PRELOAD=foo.so
(gdb) set sysroot /location/of/foo.so/
(gdb) set solib-search-path /location/of/foo.so/

Also doing the following doesn't work:
(gdb) r LD_PRELOAD=foo.so bar

I was wondering if anyone had any idea on how I can set the environment remotely through gdb? IN the mean time I know 
that I can use gdb locally on the target machine. And I can also create a wrapper application that sets LD_PRELOAD via 
execve() and start by debugging that. I was just hoping there would be some feature of gdb, or Momentics, that someone 
knew about.

Thanks
