   Anyone played around with this patch yet? Anyone have something 
committable?

   Here are some of my comments on it:

   * Rule boost-install() seems to have an echo call leftover from some 
debugging/development effort.

   * What is the install-proper-headers target? Or more precisely, what 
is the install-proper stage target and how does it relate to the install 
stage target created in the boost-install() rule.

   * Not sure if your question 'where does the install-headers target 
get created' is still an active one but as I see it it gets created in 
the very same package.install() call that uses it.

   If this is a valid patch that actually does solve a real usability 
problem with the Boost library's build, I'd hate to see it fall through 
the cracks.

   I committed parts of the patch related to the tools/package.jam 
module and that module truly did have an extra grist part in some of the 
path properties passed to its underlying worker stage rules. Why & how 
that ever worked I have no idea :-) but am too lazy to check right now.
