No problem!

It seems like presense of "import order" in gcc.jam has masked this problem in 
my testing. Should be fixed now.

The strange thing is that it works with gcc. Eh... I see the following in 
sun.jam:

flags sun.link LIBRARIES <library> ;

I think that's the bug. The <library> feature is processed specially: some 
libraries are added to sources and some (exactly, searched), are represeted 
as <find_shared_library> feature. The code above adds all <library> values to 
LIBRARY varaible which is then added to sources.

BTW, gcc.jam has

flags sun.link LIBRARIES <library-file> ;

instead. Maybe you change change <library> to <library-file> and report the 
results?
