Works for me. You can easily check whether the import path is passed to qml/qmlscene by setting the "QML_IMPORT_TRACE" environment variable to some value under Run Settings, Run Environment.

Getting QML import paths right is actually quite tricky due to the rule that the uri set in the qmldir and the local directory tree must match. This goes a bit against Qt Creator's philosophy to do shadow builds, and not adding an 'install' step by default...
If you used the default settings in the wizard and have the uri "com.mycompany.qmlcomponents" make sure that your qmldir file and .so file ends up in the directory "com/mycompany/qmlcomonents" underneath the path you set in via 'importPaths' ... The extension plugin created by Qt Creator actually doesn't do that automatically, but instead copies the files to Qt's 'qml' directory when running 'make install'. You can tweak the path it installs to in the .pro file.
With these changes, the setup you described works for me. Maybe we should indeed add a 'make install' step by default in the Qt Creator wizard ... Feel free to create a suggestion on bugreports.qt-project.org, so it's not forgotten (it's too late for 3.0 certainly).
