Ok, then they get pulled in if your -dev package is installed. (And if
you have kernel modules in your package, that doesn't sound too
suprising).

Ok. So something needs those .so-files, and if they're pacakged in your
-dev package, it'll be pulled in.
Normally, libraries are assumed to be versioned, i.e. library.so.X.Y,
with the library.so file being a symbolic link pointing to the versioned
ones. The link is packaged in -dev and the real libraries in the main
package.
If you have non-versioned libraries, then you need to ensure that those
are installed in you main package; just as you did.

What get's installed is the packages that you specify, and all of their
runtime dependencies.
