Thanks for replying Tim, and as you can see I'm back in emacs.

I know that building emacs isn't part of org-modes mailing list setup, but it 
looked like '(require 'ob-tangle)' was causing the problem, hence I asked the 
org-mode mailing list.
  
For the benefit of the archives these are the steps I took -
  
  ====
make clean
make distclean
sudo make clean
sudo make distclean
delete /home/foo/git/emacs
git clone -b master git://git.sv.gnu.org/emacs.git    
cd git/emacs
git checkout origin
git checkout emacs-29
/autogen.sh
configure
make
src/emacs -Q ;;; if this works, then try loading emacs, and if that works, then 
bobs your uncle!
sudo make install
  ====

This is because I'd got a failed build and install, so it all needed clearing 
out before I could delete the failed emacs git download, so it needed a fresh 
download.

Anyway, I've learnt from my mistake and have documented it all just in case I 
do it again.

Thanks    
  Sharon.
