when I tried your script it prompted that there might be tab instead of eight spaces. So I inserted 8 spaces there, but it still prompted the same. Also I couldn't understand the script (particularly $(MAKE) - what does the variable stands for? also the rest of the code after "depend.depend.dep"). If you can explain the script, I shall know how to edit the script for my file.
