GUB does something like
error = process(cmd, log_filename)
if error:
print "something went bad in", cmd
process("tail " + log_filename)
I really like that system -- you get a small glimpse of what went
wrong, but you still have the entire file there for your viewing
pleasure.
(that's particularly useful for me, since my general reaction when
something breaks is to look at a few directories, which 1) is
completely useless, and 2) scrolls the actual error messages out
of the xterm history!)
I have no clue how to achieve this kind of thing in make, though.

Exactly the same phrase in English! We probably stole it from
you. :)
