The only problem *I* know about with  -j is that it sometimes misses
dependencies on generated headers (with Boost.Build V2, V1 does not handle
generated headers well itself). But this should not affect Boost.

Can you specify exactly what kind of problems you get? Note that for distcc
to work reliably, you need to have exactly the same version of the compiler
on all hosts, and preferrably a stable version. I used to get segfaults
otherwise.
