  Thank-you very much Ben - got that approach to work (eventually :-)

  I tried:
      dpkg-buildpackage  -Pcross,nopython -aarmel -B -uc -us

  First I got several dependancy complaints that were not valid. The
components that
  dpkg-buildpackage complained about were apparently already installed
according to

    apt-get install libssl-dev libglib2.0-dev libudev-dev libwrap0-dev
libpci-dev gcc-5-arm-linux-gnueabi:native

  So I tried it with -d  and got *lot* of compiling ending with the failures and
  requiring some missing parts to be installed...

  * missing arm-linux-gnueabi-gcc - installed the package gcc-arm-linux-gnueabi
  * missing openssl/opensslconf.h: - installed libssl-dev:armel
  * missing libpci - installed libpci-dev:armel
  * missing libwrap - installed libwrap0-dev:armel

    Glad I found out about the -nc option to avoid the lengthy
rebuilding from scratch...

  * Hmm apparently the complaints were valid - but for the armel packages!

Thanks again.

        Andrew
