I've tried to set things up so that if BZIP2_INCLUDE is defined, it will be
added to the compiler's list of include paths. This is the relevant section from
bzip2.jam:

  template bzip2
    : # sources
      ...
    : # build requirements
      [ unless $(NO_BZIP2) : <include>$(BZIP2_INCLUDE) ]
      ...
    : # build variants
    ;

Here NO_BZIP2 should only be true if it has been explicitly set, if
NO_COMPRESSION has been explicitly set, or if you are running Windows and
several other conditions are satisfied.

As I understand, the above should cause -I/usr/local/include to be added to your
command line. Unfortunately, I arrived at this scheme by trial and error and all
I can say is that it works on my Windows system. All the other regression
runners have either set BZIP2_SOURCE explicitly or are letting the compiler find
the headers and binaries automatically.

I don't think so. I'd say there's a 99% chance it's an error in my Jamfiles.
