PCL project does not build after Mono 3.2.7 update (Help)

Hi!

Just updated to Mono 3.2.7 and PCL project won't build:

Microsoft.Portable.CSharp.targets
/Users/miha/work/Project.Portable.Core/Project.Portable.Core.csproj: Error: /Users/miha/work/Project.Portable.Core/Project.Portable.Core.csproj: /Library/Frameworks/Mono.framework/Versions/3.2.7/lib/mono/xbuild/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets: Project file could not be imported, it was being imported by /Users/miha/work/Project.Portable.Core/Project.Portable.Core.csproj: /Library/Frameworks/Mono.framework/Versions/3.2.7/lib/mono/xbuild/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets could not import "$(MSBuildToolsPath)\Microsoft.Portable.CSharp.Targets" (Project.Portable.Core)

The contents of /Library/Frameworks/Mono.framework/Versions/3.2.7/lib/mono/xbuild/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets are:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Import Project="$(MSBuildToolsPath)\Microsoft.Portable.CSharp.Targets" />
</Project>

Any ideas how to fix this? Please?
