Well, I guess we never really talked about that ;-)
Jens and I spent some time together working out the issues, though. I think
we'll have something soon enough.

It works for me. Are you sure? If so, what output do you get?
What is the result of "jam -sBOOST_ROOT=... -n -a" (using the latest version
of jam from CVS), or
jam -fallyoubase-path -n -a (using earlier versions)?

Ah, yes, fixed now. In case I haven't checked in yet, the fix is as follows:
# in boost-base.jam
$(SHELL_SET)PATH=$(RUN_PATH) # changed
$(SHELL_EXPORT)PATH # added
The issue is related to the fact that on some Unix shells, you can't set and
export a variable in one swell foop. When I discovered that, the MSVC
SHELL_EXPORT = "set " ;
SHELL_SET = "set " ;
SHELL_EXPORT = ; # everything is exported
But since the Run action was still just using SHELL_EXPORT, the PATH
variable was not being properly set up. Understood?

Nope, and we still don't know how to explain the first one.
