Heh, sorry for further derailing this thread, but I just couldn't help myself 
Back on topic: I assume you know that you have to save your bsp to the $SteamUserDirportal 2portal2_dlc1maps folder, right?, otherwise building cube maps will not work.
This has been an issue since the DLC release, but I thought I'd mention it just in case you didn't know.
See this post / thread for details.
It is also important not to rename the bsp after building cube maps, or they will stop working.
