How to specify explicit requires on library

Title: Konsole output

  
    Hello,

    
    I was looking at the gdal spec [1] and noticed the following lines
    in %prep

    
    # libproj is dlopened; upstream sources point to .so, which is
    usually not present

    # http://trac.osgeo.org/gdal/ticket/3602

    sed -i 's|libproj.so|libproj.so.0|g' ogr/ogrct.cpp

    
    The problem is that a libproj soname bump will be silently missed
    unless a maintainer remembers the existence of this particular line
    - and indeed, the libproj soname was bumped in proj-4.9.1 to
    libproj.so.9.

    
    I was about to file a bug suggesting

    
    # Major digit of the proj so version

    %global proj_somaj 9

    [...]

    # proj DL-opened in ogrct.cpp, see also fix in %%prep

    Requires: libproj.so.%{proj_somaj}

    [...]

    sed -i 's|libproj.so|libproj.so.%{proj_somaj}|g' ogr/ogrct.cpp

    
    but I haven't found how to correctly specify the explicit
    arch-correct requires on the library. I suppose I want something
    which will ultimately results in something like

    
      libproj.so.9()(64bit)

      
    but how can the "()(64bit)" part be specified?

        
        Thanks,

        Sandro
