Looks like another case of "the unix makefiles/.cbp is out of date" phenomenon :?...
DebuggerState is a relatively new part of the debugger plugin, and seems to not have been added to whichever build method you used (and quite possibly not to the other one either).
Oh, and I very much doubt it's actually RC2 as you claim, as DebuggerState was added to version control on Nov 23rd, and according to the main page RC2 was released Oct 25 (about a month earlier
EditPairDlg is also quite recent (Nov 25).
Since the debugger plugin needs DebuggerState and the compiler plugin needs EditPairDlg according to your error message, that would explain why those menus aren't available: the plugins that should create them couldn't be loaded.
