  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
