[ 63 of 338] Compiling Agda.Utils.FileName ( src/full/Agda/Utils/FileName.hs, 
dist/build/Agda/Utils/FileName.o )

src/full/Agda/Utils/FileName.hs:42:28: error:
    • No instance for (Hashable Text)
        arising from the 'deriving' clause of a data type declaration
      Possible fix:
        use a standalone 'deriving instance' declaration,
          so you can specify the instance context yourself
      There are instances for similar types:
        instance Hashable text-1.2.3.0:Data.Text.Internal.Text
          -- Defined in ‘hashable-1.2.7.0:Data.Hashable.Class’
        instance Hashable text-1.2.3.0:Data.Text.Internal.Lazy.Text
          -- Defined in ‘hashable-1.2.7.0:Data.Hashable.Class’
