Comment (by ryandesign@…):

 Thank you, but I want to continue using MacPorts libraries as much as
 possible, not the bundled ones. In particular, I want to continue using
 MacPorts boost, so as not to reintroduce the problems we faced when using
 the bundled boost last time (last year); see #38334 wherein those problems
 are described. I agree that most of the patchfiles are no longer necessary
 with 2.6.0, however one of them is what made scons able to find the
 MacPorts libraries; it's that patch that I need to scrutinize to see how
 to adapt it to the 2.6.0 SConscript.
