[Boost-build] [v2] Python install root(s)

I want to configure our site.jam so that we can pass multiple python 
install roots to the init rule.

using python : 2.3 : /usr/local /usr/netpub/python-2.3.5 
/usr/engsci/python /usr ;

In our case, the location of the correct python depends on which 
machine we log in to on our Lan.  I'd like to search the install roots 
in the order passed to init until a valid version is found.  
Fortunately for us, our Pythons are all the same version, not sure what 
we'd do if the versions changed based on the system we logged into.  
The python init rule

rule init ( version ? : root ? : includes ? : libraries ? : 
cygwin-condition * )

currently permits only a single root.  Is this a reasonable approach or 
are there better solutions?

Thanks.
