Two problems:

the message:

  BUILD:   Doing 'make -j1' parallel build

Looks funny: 'parallel' && -j1? :-)

This is on fedora12, on a kvm guest, nfs mounting /home/acme/git, all works
well up to the liblk.a part, cloning it to do it without NFS to continue
testing the integration of acme/perf/core with the build speedup patches.
