I just tried building Sage from source on a PARC machine. On this
machine, my home directory is an NFS-mounted share. The build fails
with a shower of messages of this form:
Build finished. The built documents can be found in /local/sage-4.7.2/
devel/sage/doc/output/html/en/numerical_sage
Traceback (most recent call last):

Can this safely be ignored?
