After reading the thread, I realize that I do not actually want externam 
dependency files moved to hg. I and others are not going to push changes 
back, so we do not need hg clones.

What would be good would to be able to access the files and use them to 
build python without svn installed. I don't know the best way to do 
that, but if tarred or zipped releases were made for each version that 
should be downloaded, our urllib, tarfile/ziplib, and any other modules 
needed should be sufficient to transfer and unpack.
