Comment (by leif):

 Since we're going to ''generate'' the effective `Makefile` anyway, I
 wouldn't patch `deps`, but only put dependencies (as its name suggests)
 into it, and flexibly generate the build ''rules'' on-the-fly, depending
 on what output / verbosity level is currently requested.

 I.e., `deps` would just contain lines like
 {{{
 #!make
 $(INST)/$(ATLAS): $(BASE) $(INST)/$(LAPACK) $(INST)/$(PYTHON)
 $(INST)/$(PATCH)

 $(INST)/$(BOEHM_GC): $(BASE) $(INST)/$(PATCH)

 $(INST)/$(BOOST_CROPPED): $(BASE) $(INST)/$(PATCH)

 $(INST)/$(CLIQUER): $(BASE) $(INST)/$(PATCH)

 $(INST)/$(TERMCAP): $(BASE) $(INST)/$(PATCH)
 }}}
 or, preferably:
 {{{
 #!make
 $(ATLAS): $(BASE) $(LAPACK) $(PYTHON) $(PATCH)

 $(BOEHM_GC): $(BASE) $(PATCH)

 $(BOOST_CROPPED): $(BASE) $(PATCH)

 $(CLIQUER): $(BASE) $(PATCH)

 $(TERMCAP): $(BASE) $(PATCH)
 }}}
 Or, for the example given:
 {{{
 #!make
 $(ATLAS) $(BOEHM_GC) $(BOOST_CROPPED) $(CLIQUER) $(TERMCAP): $(BASE)
 $(PATCH)

 $(ATLAS): $(LAPACK) $(PYTHON)
 }}}

 (In general, one could write ''a single'' `make` rule for building /
 installing all spkgs, probably with some changes to the directory
 structure though.)
