propagation of usage-requirements

I have a problem with the propagation of usage-requirements:
My Jamfile looks like this:

<Jamfile>
alias foo_dependencies : /user-config/some_external_lib ;
lib libfoo : foo.cpp foo_dependencies ;
exe bar : bar.cpp libfoo ;
</Jamfile>

and my user-config.jam looks like
<user-config.jam>
alias some_external_lib : : : <include>some_dir ;
</user-config.jam>

No I would expect that if I build 'bar', the 'some_dir' include 
directory is also passed on to the compiler. This is necessary because 
bar depends on foo and foo includes headers of the external library. 
However only the 'some_dir' is searched for include files when compiling 
foo.cpp but while compiling bar.cpp ;-(
