I think you've over-engineered your Jamfile ;-) Really, "log4cplus" that you 
specifiy as source of BASDiagnostic is not linked into that object, it's 
just merely passed though to libported which uses that library during 
linking. In other words, adding log4cplus to sources of libported won't cause 
any problems whatsoever. 

However, I noticed that the problem is caused by somewhat contrived method 
<search> is handled and decided to simplify it. Code is not 10 lines shorter 
and your use case works.

The fix and a testcase were just committed.

Yes, that's expected.
