1 error
*** Error code 2
The fact that there's no actual error message shown indicates that
you're doing make installworld with a -j option.  This is not
supported and as you have found is likely to fail.

The lack of an error message did seem odd. Thanks for the heads up.

Is the Handbook out of date?  According the Build World section:

<quote>
It is now possible to specify a -j option to make which will cause it to
spawn several simultaneous processes. This is most useful on multi-CPU
machines. However, since much of the compiling process is IO bound rather
than CPU bound it is also useful on single CPU machines.

On a typical single-CPU machine you would run:

    # make -j4 buildworld

make(1) will then have up to 4 processes running at any one time. Empirical
evidence posted to the mailing lists shows this generally gives the best
performance benefit.

Let me give it a try without `-j'.

Time it when you do the buildworld such as "time make". There are a lot of us with newer HDs and cpus that have found that no "-j" produces a wall clock time that is 10-20% faster than -j4.
