In both these cases, I manually created unversioned symlinks to those

The official way to get the unversioned symbolic links is to install
the -dev or -devel package for that library. Of course, you're not
supposed to require end-users to do that.
Does not always work, e.g. in the case of Debian. -dev will install the
.h and .a files, but won't necessarily set up unversioned symlinks.
I've never found a -dev package that doesn't set up symlinks in many
years of using Debian for development. (Except if only static versions
of a specific library exists, obviously). Could you give an example?
[Checks a couple of systems] I can't be /absolutely/ certain without
building a system from clean, but the thing that regularly bites me is
the PostgreSQL client library and I've recently been bitten by libcap2.
However, I suspect that in both cases I might have set up a symlink
myself and later installed the -dev package, I don't have an easy way of
reconciling usage of ln -s (logged in root's .bash_history) with the
date a package was installed (which I log into RCS). So I might have to
recant, or to deprecate my testimony as unreliable :-)
I do agree with Graeme's position though: a -dev is described as
containing files for developers, and it should not be necessary for a
non-developer user to start encumbering his system with .h files etc.
What's more, part of the reason that I've had to create symlinks
manually in the past is because things like (if I recall correctly)
OpenOffice's interface to PostgreSQL require libpq.so without declaring
-dev as a prerequisite... which rather reinforces my position that this
is a distro issue even if they prefer to disclaim it.
