[Boost-build] Weirdness with "embedded" rules

In the attached package there is a project copied from the tutorial,
with a simple modification.

I tried, on a simple project, the following trick:

lib network
    :
        [ glob *.cpp ]
        [ lib ws2_32 ]
    ;

and it worked: ws2_32.lib was linked in.

But that, for some reason, disturbs the use of alternatives for a
target. Calling bjam in the attached project directory I get:

[pedro_at_localhost test2]$ bjam
/home/pedro/Projetos/boost-build-cvs/build/feature.jam:430: in
validate-value-string from module feature
error: "msvc" is not a known value of feature <toolset>

/home/pedro/Projetos/boost-build-cvs/kernel/bootstrap.jam:132: in
boost-build from module
/home/pedro/Projetos/boost-build-cvs/boost-build.jam:2: in module scope
from module

I get this result with both M11 RC2 and latest CVS.

Is that "embedded" [ lib ] correct?
Am I missing something?

I do see workarounds to the same effect.
It's just that Boost.Build promises so sweet easiness, just to take it
away later...
