I don't think you need to bother, as building bjam takes about zero
time. Furthermore, bjam is not changed very often, so you may use
the last released version.

No, I mean "using darwin ; "

The version of gcc provided by apple goes by the name 'darwnin'. You'd
need 'gcc' toolset only if you have a FSF gcc somewhere.

Is the error message *exactly* the same? Or it now complains about 10.1?

Oh, you have 10.1 too? Please update, make sure tools/build/v2/tools/darwin.jam
is of revision 47164 and try again.
