[MonoDevelop] Build problem in MD 3.0.4.2

[Elmar Haneke]

After downloading MD 3.0.4.2 ./configure stopps with error:

    config.status: creating
    src/addins/MonoDevelop.Debugger.Soft/MonoDevelop.Debugger.Soft.AspNet/Makefile
    config.status: creating src/addins/MonoDevelop.HexEditor/Makefile
    config.status: creating src/addins/MonoDevelop.DocFood/Makefile
    config.status: creating src/addins/MonoDevelop.MacDev/Makefile
    config.status: creating tests/Makefile
    config.status: error: cannot find input file:
    `tests/UnitTests/Makefile.in'

What can be done to resolve that problem?
