Hi John,
Thanks for the suggestion, unfortunately I come out with the same issue, (although I also get a 'TIFF file does not contain page 0' issue as well) probably because the routine also calls the libtiff library?

Have you tried using vips to make the pyramids? It's quite commonly used to make pyramids for iipsrv and friends.
There's a windows binary built against libtiff4 here:
http://www.vips.ecs.soton.ac.uk/supported/7.24/win32/
You need vips-dev-tiff4-7.24.5.zip. If I run this on my laptop with:
$ time vips.exe im_copy bigger8.v bigger.tif:,tile,pyramid,,,,8 > build.log
real 11m35.835s
user 0m40.080s
sys 0m49.710s
I get a 9gb tif pyramid and it seems to work OK. You'll need a program that can read huge tiff pyramids as well, of course.
Documentation for the strange tiff format string here:
http://www.vips.ecs.soton.ac.uk/supported/7.24/doc/html/libvips/VipsForm at.html#im-vips2tiff
Leave the ",,,8" off the end of the string and it'll write smalltiff, though of course your filesizes will be limited.
