Comment(by leif):
This is a general error in how Cliquer is adapted to/built for Sage.
It is intended as a stand-alone program, and therefore contains
{{{main()}}}.
You '''must''' (or should) '''not''' build [shared] libraries containing
a {{{main()}}} function.
Instead, use {{{#ifdef ...}}} and {{{-D...}}} depending on what you build.
I think Sage should build and install both, the program and a library. (If
you remove/omit {{{main()}}} for the shared library, the loader problems
should vanish.)

Note the changes made to the {{{cl}}} target (which is [the name of] the
stand-alone program).
This package really needs work (but there's - besides others - already a
ticket (#9871) for an upstream update as well). The files in {{{src/}}}
are not even vanilla, but contain weird changes in order to use Cliquer as
a library from within Sage.
