[Boost-build] error: No best alternative for ./fixed_point

Subject: [Boost-build] error: No best alternative for ./fixed_point

I'm trying to repeat what I have done several times before, but get inscrutable errors from bjam.

I have created a new (normal file structure) sub-module library fixed_point at
I:\modular-boost\libs\fixed_point

and run b2 in /example successfully.

But when I try to run Quickbook in is /doc folder below, I get a slew of errors (below).

Other libraries I have tried seem to build the Quickbook docs OK.

Suggestions as to what I am doing wrong - please ?

Thanks

Paul

PS My Quickbook file is (now) reduced to skeletal.

my jamfile similarly down to

import quickbook

using quickbook ;
using boostbook ;

xml fixed_point
  :
    fixed_point.qbk   ;

xml fixed_point : fixed_point.qbk ;

boostbook standalone
    :
        fixed_point
    :
        <format>html:<xsl:param>boost.root=../../../..
   ;

I:\modular-boost\libs\fixed_point\doc>b2
