I've picked source code for an existing BizTalk 2013r2 solution that I'm trying to compile using Visual Studio 2013.
I'm hitting the following error when trying to compile a map:
Mapper Compiler: Functoid not found: guid (2de6985a-3dff-46eb-a7d8-4fc884756860) with functoid id (54009). Check if the assembly implementing this functoid is present
I've scanned all the source code I was provided with and there's no sign of any custom functoid classes. Maybe I'm missing a reference to an open source functoid library but from what I can see in the .btm file, there's not much to go on:
<Functoid FunctoidID="31" Functoid-FID="54009" X-Cell="44" Y-Cell="196" Functoid-CLSID="2de6985a-3dff-46eb-a7d8-4fc884756860">

Any ideas?
It sounds like you are missing a custom functoid. This is the reason I am not a fan of custom functoids. I prefer to put custom code in scripting functoids because it then goes with the map in source code. That custom functoid does not appear in any of the searches, for example BizTalk Server: List of Custom Functoids (Technet). So I think you are on your own.
Look for a custom assembly in C:\Program Files (x86)\Microsoft BizTalk Server 2013 R2\Developer Tools\Mapper Extensions or as bts_dev says in the GAC.
