 I have installed Python 2.6
 when i runing "bjam" i have messages:


 {{{
 warning: No python installation configured and autoconfiguration
 note: failed.  See http://www.boost.org/libs/python/doc/building.html

 note: for configuration instructions or pass --without-python to
 note: suppress this message and silently skip all Boost.Python targets
 }}}

 After I add add line "using python : 2.6 ; " to "project-config.jam" I
 have this warning message again.

 Then I add absolute path to python in "project-config.jam". This is not
 working too.

 I run bjam with "--debug-configuration" option and have messages:

 {{{
 notice: [python-cfg] running command '"C:\Python26\python.exe" -c "from
 sys import *;
 print('version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s'
 %
 (version_info[0],version_info[1],platform,prefix,exec_prefix,executable))"
 2>&1'
 notice: [python-cfg] ...does not invoke a working interpreter
 notice: [python-cfg] No working Python interpreter found.
 }}}

 But when I run
 {{{
 "C:\Python26\python.exe" -c "from sys import *;
 print('version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s'
 %
 (version_info[0],version_info[1],platform,prefix,exec_prefix,executable))"
 }}}
 manualy, I have correct results.

 Ok. Next I modify "tools\build\v2\tools\python.jam"

 {{{
 local rule shell-cmd ( cmd )
 {
     debug-message running command '$(cmd)" 2>&1"' ;
     x = [ SHELL $(cmd)" 2>&1" : exit-status ] ;

     debug-message CMD "$(cmd)" ; <<<<<<< add this string
     debug-message RESULT "$(x)" ;  <<<<<<< add this string

         if $(x[2]) = 0
     {
         return $(x[1]) ;
     }
     else
     {
         return ;
     }
 }
 }}}

 and run "bjam --debug-configuration" again

 Result:

 {{{
 notice: [python-cfg] running command '"C:\Python26\python.exe" -c "from
 sys import *;
 print('version=%d.%d\nplatform=%s\nprefix=%s\nexec_prefix=%s\nexecutable=%s'

 2>&1'

 is error text at Russian. He said what this is not correct path and shell

 }}}

 I don't know why he is trim command.
