Why does rpm built not able to find the library from the system?

Issue

• Create a package foo v1 containing a shared library (/usr/local/lib/libfoo.so) which does not set the soname
• Create a package bar using this shared library

# rpm -qRp bar.rpm | grep foo
libfoo.so

• Create a new version of package foo v2 where the shared library now sets the soname and is installed as a symbolic link from /usr/local/lib/libfoo.so to /usr/local/lib/libfoo.so.1
• The bar program built against the original verson of libfoo can find it regardless of whether the old or new version is installed.
• However, installation of bar when foo v2 is installed fails dependency checking.

error: Failed dependencies:
        libfoo.so is needed by bar

• Likewise an upgrade from foo v1 to foo v2 will fail for the same reason.
• One needs to recompile (relink) bar against libfoo.so.1.
• Shall rpm should not understand that libfoo.so is inclusive of libfoo.so.1 when checking dependencies.
• That is, the behavior of rpm should match the behavior of the OS.
