Compiling .rel-files - module search path

erlc for a .rel file calls systools:make_script/2 to generate the boot 
script. For every application, systools:make_script/2 looks for the .app 
file in the code path, and then assumes that all .beam files for this 
application are located in the same directory - ie does *not* search for 
them in the path. Could this be what is causing your problem?
