Just to weigh in on this, I'm compiling it on mac right now to see if I can find a missing header I already fixed in a local branch.  I had to twiddle CPPFLAGS and LDFLAGS on the configure line to get it to know where macports installed boost:

$ CPPFLAGS=-I/opt/local/include LDFLAGS=-L/opt/local/lib ./configure

There are established macros for requiring boost, and for specifying the location and specific versions for autoconf:


the m4 file goes into the m4 subdirectory and configure.ac gets:
