Unsupported file format... for architecture armv7

Hi,

I'm currently having a problem building my application with an open-source ANE (Freshplanet's Facebook ANE).

The ANE itself seems to be building fine; the error happens when building the application.

The error I'm getting is

ld: file was built for unsupported file format ( 0x58 0x53 0x79 0x6d 0x a 0x30 0x30 0x32 0x34 0x a 0x64 0x31 0x62 0x33 0x33 0x32 ) which is not the architecture

being linked (armv7): C:\<path>\8a5e33b0-7624-45f1-8912-b2e12ac6f924/FacebookSDK.framework/FacebookSDK for architecture armv7

Compilation failed while executing : ld64

We're building our application with Air 4.0, and I've tried changing to 3.8 and 3.9 for kicks, but to no avail.

Anything come to mind?

Thanks,

FYI, I needed to recompile the ANE because the Facebook API changed and theyhave deprecated some functions.
