Hello All,

I am running into a FileClone failure when building boost-1.33.1 on RHEL AS
5.0 32-bit.  FileClone works fine when I build *on* the machine, but I am
running into problems when building on a network filesystem.  Here is an
excerpt of the bjam output w/ -d2:

    ranlib
"/mydir/.obj/boost/boost_1_33_1-build/Linux/GLIBC_2.5/32/gcc-4.1.2/bin/boost/libs/wave/build/libboost_wave.a/gcc/release/runtime-link-static/libboost_wave-gcc-s-1_33_1.a"

FileClone
/mydir/boost/boost-1.33.1/Linux/GLIBC_2.5/32/gcc-4.1.2/lib/libboost_wave-gcc-s-1_33_1.a

    cp -fpd

Is the FileClone failing simply because permissions/ACL cannot be
preserved?  Even though the file is actually copied to the right place?

Is there a way to work around this?...maybe by disabling the "remove" step
from FileClone, or any other way?

Thanks,
Mike
