[ubuntu-mono] Missing assembly Microsoft.Build.dll

[Shatilar]

I have unstalled Ubuntu 13.10 and I can't find the package containing
the assembly Microsoft.Build.dll. If I build mono manually then assembly
is installed into the GAC.

user at user-host:~/code$ gacutil -l Microsoft.Build
The following assemblies are installed into the GAC:
