The addition of files/patch-dsh-dsh.c seems to be triggering this.
It appears to declare the 'malloc_options' symbol.  Looking at stdlib.h,
the real name should be '_malloc_options' (and including stdlib.h is the
better way to get this declaration).  This is also documented correctly
in the malloc(2) manpage.

I can't reproduce this here.  However, netbooting a VAX probably isn't
a terribly common occurrance these days.

This one gives me:

===>   Registering installation for pdflib-5.0.3_1
===>   Returning to build of grace-5.1.14_3
Error: shared library "pdf.7" does not exist
*** Error code 1

Stop in /usr/ports/math/grace.

Note that grace/files/patch-ai was recently removed, but I'm not sure if
it makes a difference.
