I think -U is used to indicate that when building sets a non-root user
is doing the build.  This, I suspect, circumvents some file ownership tes=
ts.

I don't *think* -U has anything to do with who owns the source tree.=20
I've always had my own source tree owned by me, and done all my work
under my own account.  This is known to work.
