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

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:
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

/Applications (most desktop files are here)
/bin (most files are installed here)

Thanks for any help you can give a linux newbie
