Looks like I skipped a few files:

$ ./config.status --version | head -n3
libvirt config.status 1.0.5
configured by ./configure, generated by GNU Autoconf 2.68,
  with options "'-C' 'CFLAGS=-g' '--without-network'"

Maybe I should try again and see how omitting --without-network fares.

  CC       libvirt_driver_la-libvirt.lo
cc1: warnings being treated as errors
In file included from libvirt.c:58:
/usr/local/include/gcrypt.h:1336: warning: 'gcry_ac_io_mode_t' is
deprecated [-Wdeprecated-declarations]
/usr/local/include/gcrypt.h:1337: warning: 'gcry_ac_io_type_t' is
deprecated [-Wdeprecated-declarations]
... lots more deprecation warnings

/usr/local often implies a self-built gcrypt; but then I just noticed
that my BSD VM has that file as well (I guess that's what you get when
using BSD ports) - what version are you using?  And what version of gcc,
so that we can figure out how to disable deprecation warnings from
system headers?  For that matter, what is in your file around line 1336,
since my copy of the file was not producing deprecation warnings for me,
and does not contain 'gcry_ac_io_mode_t' near line 1336.

I'll reply to these in separate email.
