I thought build was working OK on fedora f13 x86_64.  But then I noticed 
something strange:

I'm building like this:

bjam -sHAVE_ICU=1 -sEXPAT_INCLUDE=/usr -sEXPAT_LIBPATH=/usr/lib64 --
layout=tagged threading=single,multi stage 

Running 1st time, I got no errors....updated 1353 targets...

But then I reran in the same directory and got:
...patience...
...patience...
...patience...
...found 7771 targets...
...updating 96 targets...

[ rebuilt release/link-static/libboost_math_c99f.a and release/link-
static/libboost_math_c99.a ]

...updated 96 targets...

Trying a 3rd time, nothing happens.
