You mean that the 'hello' target in
'test.install installtest : [ exe hello : test.cpp ] ;' should be explicit
automatically? Sounds good to me.
But that's not really the problem. I made 'hello' inline just to save a
line in the message. I just wanted the 'installtest' target to be explicit.
Sorry for the confusion.

I just downloaded today's nightly build, just to make sure we both use the same
version. Btw, I had problems downloading the .zip file, so I used the .tar.bz2
version.
bjam --debug-configuration shows the correct paths.

You mean the test project? Please find test.zip attached to this message.
I now wrote "exe hello..." as you did above, with the same results as
before -- common.copy is called.
It's strange that you get results different from mine. Could it be that I need
a newer version of bjam? 'bjam --version' prints

Boost.Build V2 (Milestone 10)
Boost.Jam 03.1.13

Btw, when I use the stage.install rule directly, as in

# file Jamroot
import stage ;
exe hello : test.cpp ;
stage.install installtest : hello ;
explicit installtest ;
# EOF

everything works as expected.

Thank you for your help,

Klaus
