the list of files is constructed by using 
solist=$(echo $filelist | grep "\\.so" | grep -v "^/lib/ld.so" | \
        xargs file -L 2>/dev/null | grep "ELF.*shared object" | cut -d: -f1)

In general it is not a problem, but I think that this should be avoided.
It has been already pointed out in lists, and in numerous package
submissions (I always look for sane provides and for perl packages
there are the 'usual bogusprovides on .so files'). I just have filled a 
bug against rpm:


Another possible solution would be to avoid setting the SONAME for the
files that are only to be dlopened. libtool always set the soname, and it
seems to be the same for perl. Maybe this is where things should be
