build failure in [build SAX]

Greetings,

I am trying to do a clean build of master commit c967872, fetched
around 2014-10-12 12:50 UTC and still current as I write this,
configured:

    CXXFLAGS=-std=c++11 --enable-option-checking=fatal
    --enable-dbgutil --enable-crashdump --without-system-postgresql
    --without-myspell-dicts --with-extra-buildid --without-doxygen
    --with-external-tar=/home/terry/lo_hacking/git/src
    --disable-gstreamer --enable-gstreamer-0-10

on debian-wheezy 64-bit.  This is my first time using parameters
CXXFLAGS=-std=c++11 --disable-gstreamer --enable-gstreamer-0-10.


The build fails in the first [build SAX].  Trying again with `make
verbose=t` ends at the same step with messages:

    [build SAX] CustomTarget/i18npool/localedata/localedata_en_AU.cxx

    ERROR: Cannot open uno ini file:///home/terry/lo_hacking/git/libo4/instdir/ure/lib/unorc

The file reported to be absent is indeed absent.


Advice welcome, both about how I might get on with the build and about
anything I should have done to help myself.


Thanks,
Terry.
