Ooops, a small oversight in the INSTALL file: The target "install"
depends on "all", so you don't have to issue a "make all" (or the
equivalent "make") before a "make install".

Things should be even easier if you have GNU make (IIRC), because it
is smart enough to re-read included Makefile fragments if they have
changed due to the execution of a rule. So for GNU make you can simply
say "make depend all" or "make depend install". But I haven't tested
that...
