Some time ago I stumbled accross a simmilar problem in test of 
ptr_container. The error is triggered when the serialization tests
are required, but are not supported by the library. In turn the
serialization depends on spirit which is not available for this 
compiler. However I do not exactly understand the meaning of the
generated error message that is shown above. Nevertheless I was
able to fix this problem, so the regressions are not completeley broken.
All other available tests are compiled.

My fix was to explicitly have boost build skip the build in this case.
I have tried this and can check in a fix if wanted.

But to be honest, I think this is a general problem which should be
solved in a more generic way by the build system. I.e. give a means
to skip a build when some dependency is not fulfilled.
