[TYPO3-extbase-kickstarter] Please test extension builder with TYPO3 4.6.beta-1 before we release it to TER

[Nico de Haen]

Hi,

this is most probably a caching issue. Extbase caches all php classes,
so it tries to inject the Extbase Configuration manager, but the class
file has changed inbetween and expects the ExtensionBuilder
Configuration manager.

Please clear all caches and try again.

regards,
Nico
