[Boost-build] Porting Boost 1.52.0 to OpenBSD "Duplicate name of actual target"

Hello,

I am trying to update the OpenBSD port, and I keep running into this
problem. Can somebody please guess where the problem is? I read
http://www.boost.org/doc/libs/1_52_0/doc/html/bbv2/faq.html which
discusses this "Duplicate name of actual target".

The Makefile used for compilation is at
https://github.com/jasperla/openbsd-wip/blob/7f25a653ff53a270e0873d90529791189d9715ac/devel/boost-new/Makefile

I get this error when I select threading=single,multi. If only
threading=multi is selected, the compile is fine. Please which Jamfile
or .jam should I fix to get this to produce both single and multi
threaded libs? Any other things which are needed to diagnose please
let me know and I will gladly post them.

thanks
