[1] More information is available in stderr (or sometimes stdout) if you can capture it. Another option would be to forgo the shell magic in (system cmd-string) and reimplement that call using system*, open-pipe* and friends. The "install" step could become a Guile loop over the file names. The deconstruction might likewise help you pinpoint the command that fails because the executable was not found.
