This is just a guess, but it looks like the shared library you're creating
either doesn't have a SONAME or the SONAME doesn't match the actual file
name.

You should probably read up on best practices for creating a shared
library on your platform (Linux, I presume, though you don't provide
any details about your OS, distribution, version, or RPM version, all of
which would be useful to include).

That seems to confirm that it's an issue with the SONAME.  Read up
on shared libraries on Linux and the SONAME.

PS: if this is a package you will eventually distribute to customers,
it's even more important that you follow more of the Linux conventions
for shared libraries.
