--------------------------------+-------------------------------------------
 First of all thank you for supporting SDK/deployment target in boost 1.35.

 Unfortunately, however, the current implementation assumes that the SDK
 version and the macosx-version-min always match, which is wrong. Often
 deployment target is set below the SDK target, and the assumption made by
 the darwin.jam can cause a problem (I had to set those values of my
 project to match for now as a workaround). The better proper solution is
 to have separate option for SDK path and deployment target values.

 Also, may need attention is the default values which are used in case
 those values are not specified. It is normal not to use the SDK but to
 link against the local installation itself when SDK is not specified. Also
 the gcc defaults macosx-version-min to be the system version. This, of
 course, can be substituted by taking the SDK version that matches the
 local system and specifying macosx-version-min.
