Then I would say the only thing you need is to add boost.timer as a
dependency, but this should be done by boost.test in fact (see below). The
problem of boost.thread was mainly caused by building against both shared
and static boost.test with the same sources.
In geometry apparently you are using the execution monitor (eg.
geometry/test/algorithms/append.cpp) and the header-only variant of
boost.test (eg. geometry/test/algorithms/distance/distance_areal_areal.cpp).
So the problem looks like being the link against boost.timer only.

I am very very far from being an expert of Jamfile. If you use the
boost.test with static link, I think
"<library>/boost/test//boost_unit_test_framework/<link>static" in the
requirements is enough for building it. I do not know if this is done
by "import testing".

Right, I rolled it back. I erroneously thought boost.timer being a header
only library. Apparently this worked fine on darwin.

For symbols of boost.timer missing, I would say "do nothing" as it should be
handled by boost.test. Please bug me (offline if you prefer) once you have
the test results.
