On Red Hat distributions, what lack of a .so symlink means is that you
forgot to install the readline-devel subpackage (or in general, the
-devel subpackage for whatever library is involved).  I believe Debian
uses a similar convention.

The -devel package also generally carries the include files (.h files)
you need to compile anything using the library, so I'd sort of expect
that you don't get too much further with just a manually created symlink.
