Re: zlib and bipz2 not linking?

Hi Steven,
Does this mean that the usage requirement are not being met, and therefore zlib is not being included?
The reason I ask is this line in the debug output ..

     Building target '/zlib'
         Build request: object(property-set)@2707 ...
         Command line free features: <testing.launcher>../../../status/vxworks_boost_test_run.exp
         Target requirements:

         Common properties:  ...
         Usage requirements for zlib:
         Build properties:  ...

    - zlib                     : yes (cached)
         Usage requirements from zlib:  <relevant>cross-compile <relevant>link <relevant>static-only

I find it odd that the "usage requirements from zlib:" include the two custom parameters I define in project-config.jam ?
What does 'from' indicate in this context?  A requirement that is new in some way? A requirement that is not matched?

Brian
