Comment # 1 on bug 950121 from Ismail Donmez

Obsoletes are there:

%package english
Summary:        English Traineddata for Tesseract
Group:          Productivity/Graphics/Other
Requires:       tesseract-ocr >= %{version}
Provides:       tesseract-traineddata-eng = 3.02
Obsoletes:      tesseract-traineddata-american <= 3.02
Obsoletes:      tesseract-traineddata-eng < 3.01
Obsoletes:      tesseract-traineddata-ocr-american <= 3.02
