No joy:

#<example jamfile>
extension query_py
:  # sources
    query_py.cpp
   <lib>@boost/libs/regex/build/boost_regex
   # requirements and dependencies for Boost.Python extensions
   <template>@boost/libs/python/build/extension
   ;
#</example jamfile>

With the invocation

c:\boost\libs\python\example>bjam -sTOOLS=VC7.1

I get
[snip]
LINK : fatal error LNK1104: cannot open file 
'libboost_regex-vc71-mt-gd-1_31.lib'
------------------^^

If I copy
C:\boost\bin\boost\libs\regex\build\libboost_regex.lib\VC7.1\debug\threading-multi\libboost_regex-VC7.1-mt-gd-1_31.lib
to
c:\boost\libs\python\example\ , and change it to 
libboost_regex-vc71-mt-gd-1_31.lib, query_py.pyd compiles just fine, and 
works when invoked from Python, too!
Would I had the skill to figure out the disconnect.  Perhaps someday. ;)
Thanks,
Chris
