msbuild package target issue

Question

I have an MVC 4 web app with VS2012, msbuild and am creating a build script with psake. I've created a publish profile in VS that packages up the project into a zip file. Running it from within VS works fine. However, running it from the command line, I get the following error:

Executing package Microsoft (R) Build Engine version 4.0.30319.32559 [Microsoft .NET Framework, version 4.0.30319.32559] Copyright (C) Microsoft Corporation. All rights reserved.

I have Web Deploy 3.5 installed on the box via WebPI. Any idea on how I can resolve this issue? The relevant section of the build script is as follows:

task package -depends test {    
    $csprojFile = "$solution_dir\$consumer\$consumer.csproj";   
    exec{ msbuild $csprojFile /t:Package /p:Platform=AnyCPU /p:Configuration=$config /v:q } 
}

Joy...after spending a couple of hours on this, it turns out to be as simple as adding:

/p:VisualStudioVersion=11.0

to the parameters list.
