Can Someone Help With Symlinks? Options

[caunt]

Under the hybrid Rom, a number of apps "can't find" their executables. I need help figuring out where and to what to make symlinks.

Here's an example:
a program with the following desktop file:

[Desktop Entry]
Comment=Track and Graph Data
Exec=tracker.elf
Icon=HISTOGR
Type=Application
Name=Tracker
CanFastload=0
HidePrivilege=0

installs to /opt/Qtopia (all the Qtopia 2.1 apps will do the same, so I'd like to figure this out)
On the hybrid Rom, this is physically installed to the path:
/var/mnt/card/opt/Qtopia
so the desktop entry is under /apps/Applications/tracker.desktop
and the executible is under /bin/tracker.elf

Now the desktop file is found and included on the launcher, and the graphic from the same path under /pics, is found and used. Why can't it find tracker.elf and what links do I need to add where for programs like this to be found?

In case it's helpful, all the other files are installing to the actual location of
/var/mnt/card/opt/QtPalmtop


/opt
/QtPalmtop
/apps
/Applications (most desktop files are here)
...etc
/bin (most files are installed here)
...etc
/Qtopia
/apps
/Applications
tracker.desktop
/bin
tracker.elf


Thanks for any help you can give a linux newbie
