I am personally a fan of including $(self:D) for finding boost-src which
is the location of the b2 executable. This has worked for me in the past
on Linux & Windows.

However, modular-boost still doesn't work for me as I believe the
/boost//headers target has problems. Though I haven't been able to
figure out what.
