avr-gnatprep AFAIK, should be available from your "cross-avr-binutils"
if it supported Ada, which you say doesn't. I would also expect to
find it if you built and installed it from sources.  BUT, under
Linux I can't think of a good reason to have an avr-gnatprep in
addition to a Linux native gnatprep. So maybe all you need to do
is to create a symlink from gnatprep to avr-gnatprep, where ever 
your gnatprep is installed.

On the WinAVR side, AVR-Ada builds on top of the plain "avr-gcc" 
toolset supplied in WinAVR. So AVR-Ada is designed to build an
Ada toolset, in addition to it's Ada avr libraries and code.

If you have a built version of the toolchain working already (and 
resolved avr-gnatprep), then you can skip the toolchain build in 
AVR-Ada, I would think. Hopefully you can just build the Ada AVR 
libraries and package support.

I haven't looked at the script, but you can probably edit the
script (or supply arguments) to skip the tool chain build, and 
just focus on compiling the AVR-Ada components with the toolchain 
you installed.
