First of all, try nightly build from -- it appears you
are using older version, and this code is somewhat different now, at least
the line numbers do not match.

Then, use --debug-building and --debug-loading options to see what project is
build when this error is produced. Once you figure what project is build,
check its 'use-project' statements, and whether they refer to valid locations.
If that still gives no clue, send the output with the two options above.
