If SLOT is setup correctly between ebuilds, you could check to be sure it's a specific SLOT. So in your case, pkg-1.0.2[a-z] would be slotted with e.g. pkg-1.0.2g:1.0.2. Anything depending on it would use `pkg:1.0.2`, and the pkg-1.0.3a ebuild could use SLOT="1.0.3" and be called as a dependency via `pkg:1.0.3`.
