Fòram na Gàidhlig

Having trouble unpicking what's going on in this sentence to figure out if it's a gu bheil or gur e situation:

"[It must be] [more than ten years] [since I moved to this area]."

using:

[Feumaidh] + [corr is deich bliadhna] + [on a ghluais mi chun na sgìre seo]

I'm sure it's:

Feumaidh gu bheil e corr is deich bliadhna on a ghluais mi chun na sgìre seo.

and not, as another part of my brain is trying to convince me:

Feumaidh gur e corr is deich bliadhna a th' ann on a ghluais mi chun na sgìre seo.

I think the thing is I'm not sure if the "corr is" phrase is a noun phrase.

Your first solution is the better one, because it's the one that people happen to be using. Think of the first one as a time statement ("Tha e deich mionaidean às dèidh dà uair") rather than a noun phrase, and it might make more sense. corr is a noun though, so your second sentence is also correct.
