Ok, please send us a link to the compressed install.log from the build
as well as the upgrade (it should be all in one file) and I will take
a look.
Right now I would suspect that either the spkgs you download are
corrupted or that another sage install is interfering via some bits of
the Sage environment, so please also send the output from 'env' on
that box and even better from the shell of the failed upgrade if you
still have it.
Can you make 100% sure that "hg heads" in the current Sage library
branch that you use shows only one head and that hg status does not
show any oddities?

Yeah, the main US site has gotten quite slow, even though that might
not be the cause for your slow rural connection :)
