    re-running the configure script with MAKE="gmake" (or whatever is
    necessary).  You can also try re-running configure with the
    '--disable-dependency-tracking' option to at least be able to build
    the package (albeit without support for automatic dependency tracking).
See `config.log' for more details

Going to re-run the build.

Error is fixed, it's all good now.

Sorry to block this but you need to also remove ./CU/qt-silent-install.qs from the repository to avoid leaving it as cruft...

[vadi2]

Sure, removed.
