[Boost-build] [boost_1_42_0][mac OSX] build error

Subject: [Boost-build] [boost_1_42_0][mac OSX] build error
From: Jeff Flinn (TriumphSprint2000_at_[hidden])

I'm updating to 1.42 from 1.39. The following bjam invocation(worked for 
1.39) gives the subsequent error messages for 1.42. Any help 
appreciated. I'm using boost-jam-3.1.17-1-maxosxx86.

Thanks, Jeff
