It's been a while since I did much with the E100.

Did you run:

# opkg update
# opkg upgrade

That will get you the latest copy of uhd we have tested in the E100.

If you try building a later uhd, you will need to update the fpga images
also. I suspect the image updater program needs some python modules that
are not on the E100, but you should be able to unpack the fpga image
tarball in the proper place.

Any particular reason you need a later uhd?
