The only reason this could happen if when the stage rules is passed two 
targets with the same name but with diffent properties. Now, how the 
properties differ and where the targets were created. I don't know ;-), 
because the error message is <adjenctive censored out>

Ok, I've tried to improve that I getting the following on one testcase:

error: Duplicate name of actual target: <pd>hello
error: previous virtual target { gcc%gcc.link-hello.STAGED_EXE 
{ gcc%gcc.compile.c++-hello.OBJ { hello.CPP } } }
error: created from Jamfile:2
error: another virtual target { gcc%gcc.link-hello.STAGED_EXE 
{ gcc%gcc.compile.c++-hello.OBJ { hello.CPP } } }
error: created from Jamfile:2
error: added properties: <debug-symbols>on <inlining>off <optimization>off 
<runtime-debugging>on <variant>debug
error: removed properties: <debug-symbols>off <define>NDEBUG <inlining>full 
<optimization>speed <runtime-debugging>off <variant>release

Which maybe could be formatted better, but at least have move information. 
I've comitted the change just now, and would appreciate if you show me the 
new error message.
