Example? Usually ldd says either libfoobar.so and this a real file (not
a symlink), or says lddfoobar.so.<num> and we don't need a symlink
libfoobar.so in this case.

With my patch PROVIDES and REQUIRES are generated in the following way.

1) PROVIDES includes all .so and .so.[0-9]+ shared library files
   excluding .so files which are symbolic links (Usually .so symlink
   points to appropriate .so.<number> which is already in PROVIDES => no
   duplicates).

2) REQUIRES includes shared libraries required by executable or shared
   libraries provided by the package, excluding shared libraries
   included in the package's PLIST. For examples, if both bin/bzip2
   (that requires lib/libbz2.so) and lib/libbz2.so are provided by the
   package REQUIRES will not include lib/libbz2.so.
