Hi Andrea,
I sent the whole tree of data, rather than just the raw data. If I
check my 0 level tier for pixel size, here's what I get (please excuse the
DOS, I do so miss Linux and System 5 Unix)
>FOR %f IN (*.tif) DO gdalinfo %f | grep Pixel >> temp.txt
> more temp.txt

I get a range of pixel sizes from my 0 level tier at 0.5 feet to my 5th
level tier at 16 feet.
This is the result I expect when I run gdal_retile. Is this not what the
extension expects to see?
Thanks,

I looked into this file briefly and found the issue, the files at the lowest
level have different pixel resolutions.
I can be seen by running on a Linux/Unix command line the following command,
which extracts the pixel size from the gdalinfo output on each of the tiff
files in the root directory.
find . -name "*.tif" -exec gdalinfo {} \; | grep "Pixel Size"
The result is:
Pixel Size = (0.500000000000000,-0.500000000000000)
Pixel Size = (0.500000000000000,-0.500000000000000)

As you can see there's a hodge podge of different resolutions, I'm not
surprised the pyramid plugin is not working.
How did you get this mixture? :-)
