module-name.rule-name not in global namespace

[Md Abdur Rahim]

The example provided ​here doesn't work in bjam. Here's what i see:

$ cat test.jam 
module my_module
{
    rule salute ( x ) { ECHO $(x), world ; }
    rule greet ( ) { salute hello ; }
    greet ;
}
my_module.salute goodbye ;

NOCARE all ;
$ bjam -f test.jam
hello, world
test.jam:7: in module scope
rule my_module.salute unknown in module 

I've attached a patch that fixes this issue. Let me know if i'm doing something wrong.
