[Boost-users] How to debug? - Unable to load Boost.Build: could not find build system.

Hello,

I've followed the instructions from here:

http://www.boost.org/boost-build2/doc/html/bbv2/installation.html

I can build from example hello.cpp from:

/usr/share/boost-build/example/hello
$ bjam
...found 9 targets...
...updating 5 targets...
MkDir1 bin
MkDir1 bin\gcc-mingw-3.4.5
MkDir1 bin\gcc-mingw-3.4.5\debug
gcc.compile.c++ bin\gcc-mingw-3.4.5\debug\hello.o
gcc.link bin\gcc-mingw-3.4.5\debug\hello.exe
...updated 5 targets...
/usr/share/boost-build/example/hello
$ ls
Jamroot  bin  hello.cpp

/usr/share/boost-build/example/hello
$ find .
.
./bin
./bin/gcc-mingw-3.4.5
./bin/gcc-mingw-3.4.5/debug
./bin/gcc-mingw-3.4.5/debug/hello.exe
./bin/gcc-mingw-3.4.5/debug/hello.o
./hello.cpp
./Jamroot

I copy the example directory to my h drive and edit the
../boost-build.jam so it points to the build system:

/h/workspace/example/hello
$ cat ../boost-build.jam

boost-build /usr/share/boost-build/kernel ;

Then I run bjam and get an error saying it can't find bootstrap.jam.
/h/workspace/example/hello
$ ls
Jamroot  hello.cpp

/h/workspace/example/hello
$ bjam
Unable to load Boost.Build: could not find build system.
---------------------------------------------------------
h:\workspace\example\boost-build.jam attempted to load the build
system by invoking

   'boost-build /usr/share/boost-build/kernel ;'

but we were unable to find "bootstrap.jam" in the specified directory
or in BOOST_BUILD_PATH (searching /usr/share/boost-build/kernel,
/usr/share/boost-build).

Please consult the documentation at 'http://www.boost.org'.

bootstrap.jam is contained in /usr/share/boost-build/kernel
$ ls -l /usr/share/boost-build/kernel
total 18

-rw-r--r--    1 mtse     Administ     4287 Dec 19 16:08 bootstrap.jam

-rw-r--r--    1 mtse     Administ    11414 Dec 19 16:08 modules.jam

$ env | grep BOOS
BOOST_BUILD_PATH=/usr/share/boost-build

What could be wrong? How can I debug this?
