Nope. This is ELF sharedlib juju.

At compile time the linker looks for libfoo.so. It reads the SO_NAME, 
which is libfoo.so.x (or libfoo.so.x.y.z), from libfoo.so (which is just 
a symlink to libfoo.so.x); Later, at run-time, the dyld loads libfoo.so.x.

RPM's packaging rules say that libfoo.so.x (and libfoo.so.x.y.z) belong 
in the foo.rpm, but the libfoo.so symlink belongs in the foo-devel.rpm.

IOW a run-time only install only needs libfoo.so.x or libfoo.so.x.y.z.

A developer who wants to link with the lib needs the -devel rpm with 
libfoo.so.

The purist packagers like this because it keeps the file system from 
being filled with lib*.so symlinks that aren't needed except by developers.

Debian/Ubuntu-style dpkg has similar rules for their -dev dpkgs.
