The top of your log file would probably point that you are using your
original X binary - unless it alos reports 1.4.99.1 then something is
mismatched.

FWIW, I would have compiled everything with a --prefix configure option
outside of your /usr tree.... (e.g. --prefix=/opt/newx). YOu would have
needed to set PKGCONFIG_DIR (or something like that) so that subsequent
configures/compiles will find previously configured/compiled stuff but
that's easy enough.
