I am trying to use new nuget feed for Sitecore 9.1.0 - https://sitecore.myget.org/F/sc-platform-9-1/api/v3/index.json and when running next command:

install-package Sitecore.Kernel -IgnoreDependencies

I am getting an error:

install-package : Failed to add reference. The package 'Sitecore.Kernel' tried to add a framework reference to 'sysglobl' which was not found in the GAC. This is possibly a bug in the package. Please contact the package owners for 
assistance.
  Reference unavailable.

I can confirm that I have latest (at the moment) .Net Framework 4.7.2 SDK installed on my PC and my VS project is targeting 4.7.2 as well

Is it a package error?
