But I don't think Boost.Jam gets updated that often, but I'm building  
each time (and cleaning afterwards).  I wonder if there's a way to  
use "svn info --xml" to get the date of the last Boost.Jam repository  
update, do some comparisons, and use that to activate the need for a  
rebuild.  (My scripting skills are minimal.)

Do you mean changing the "using gcc ;" line to "using gcc : : :  
<linker-type>darwin ;"?  But doing "bjam-svn --help gcc.init" makes  
it seems that the "linker-type" should have been chosen by default?

..

Hmm, doing that change made it work!  However, I got a help message  
from doing "bjam-svn --help darwin.init" too.  Does this mean I  
should add a "using darwin ;" line in my user-config.jam?  Would that  
line complement or replace the current GCC line?

Building the Hello example after my last SVN update didn't change  
anything.  Are you assuming that I'm actively using the 10.2 SDK?   
I'm not, but...

..I have all of the SDKs I can support.  I'm on a Mac OS X 10.4  
(PowerPC) system.  The versions of XCode that my OS supports can  
retain multiple SDKs.  Besides the native 10.4 (Universal) SDK, I  
also have the SDKs for 10.3.9, 10.2.8, and the super secret 10.1(.5?) 
[1] loaded.  So far, I've only used the native 10.4 one.  Boost.Build  
must be able to deal with the presence of multiple SDKs, and  
(generally) pick the latest; if it can't, then a bug report needs to  
be filed.

I don't have a 10.5 system, but the setup has changed from what I've  
read.  The version of xcode that come with 10.5, xcode 3.0, made a  
clean break from sub-10.5 systems; they will only build 10.5  
programs.  The last version of xcode for 10.4, xcode 2.5, is made to  
be loaded onto a 10.5 system (in a separate directory) to serve all  
sub-10.5 programming needs.

[1] The sub-10.4 SDKs are targeted to the last free point-version of  
each line.  There's no 10.0 SDK because 10.1 was a free upgrade from it.
