Can you open a trac ticket (on trac.einsteintoolkit.org), and attach your
complete option list, as well as all of the output of the Cactus configure

> A quick question about hwloc:
> We are trying to building an ET executable on a new machine, using
> HWLOC_DIR = BUILD in the .cfg file, as we want to use the bundled hwloc.
> The build of the ET succeeds, but when simfactory builds the utilities, we
> get the following error:
> Copying hwloc-bind from /usr/bin/hwloc-bind to /home/vass/Cactus/exe/sim
> Copying hwloc-calc from /usr/bin/hwloc-calc to  /home/vass/Cactus/exe/sim
> Copying hwloc-info from /usr/bin/hwloc-info to  /home/vass/Cactus/exe/sim
> Copying hwloc-assembler-remote from /usr/bin/hwloc-assembler-remote to
>  /home/vass/Cactus/exe/sim
> make[1]: *** *No rule to make target '/usr/bin/hwloc-ls', needed by
> '/home/vass/Cactus/exe/sim/hwloc-ls'.  Stop.*
> So apparently, the build process of the utilities still searches for hwloc
> executables in /usr/bin, although we specified to build hwloc in the .cfg
> file. Shouldn't it actually use the built binaries?
> It then fails copying hwloc-ls, which does not exist.
> How can I tell the build system to actually use the hwloc binaries we have
> built?
