John,
I've sent you an email about this recently, did you miss it?

I attach that email just in case.

Hi John,
sorry it took me a bit of time to get back to you about it.

Please take a look at attached project. When I run it with "bjam -n", the link 
line for the executable includes the -L command line option for the library.
(I did not add any content for the files, so running without "-n" is not going 
to do anything interesting)

You should be able to adjust your test Jamfile using that code -- just make 
sure you use "autolink-lib" instead of "lib" everywhere.

Please let me know whether this works for you.

Thanks,
Volodya
