Issue with pkg_info on NetBSD 5.1/x64

["J. Alexander Jacocks" <jjacocks%gmail.com@localhost>]

I'm having a weird issue with pkg_info, with pkgsrc 2011Q3, on NetBSD
5.1/x64.  When I try to install the 'xfce4-extras' meta-pkg, I get the
following:

$ make install
===> Skipping vulnerability checks.
WARNING: No /var/db/pkg/pkg-vulnerabilities file found.
WARNING: To fix run: `/usr/sbin/pkg_admin -K /var/db/pkg
fetch-pkg-vulnerabilities'.
===> Installing dependencies for xfce4-extras-4.6.1nb12
==========================================================================
The following variables will affect the build process of this package,
xfce4-extras-4.6.1nb12.  Their current value is shown below:

        * FAM_DEFAULT = fam
        * JPEG_DEFAULT = jpeg

Based on these variables, the following variables have been set:

        * FAMBASE (defined, but empty)
        * FAM_TYPE = fam
        * JPEGBASE (defined, but empty)
        * JPEG_TYPE = jpeg

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/usr/bin/make clean' after
the changes.

Stop.

When I look at the core file, with gdb, I see:

$ gdb /usr/sbin/pkg_info ./pkg_info.core

(gdb) quit

So, there are really no usable symbols that I have found, in pkg_info.
 I have tried both the 'pkg_info' binary that comes with NetBSD 5.1,
and the one installed by bootstrapping pkgsrc, and both behave the
same way.

Any suggestions?  My first thought is bad memory, but I've used the
memory and the other system hardware quite a bit, with no other
segfaults.

Thanks!
