Yes, that's a known bug in the automake/libtool combo.  You have to list
libraries in one Makefile in one automake variable in dependency order.
Sorry you had to find out the hard way.

Between different variables (say, lib_LTLIBRARIES and pkglib_LTLIBRARIES)
currently there is no guaranteed installation ordering at all.  Between
different Makefiles of a package the traversal order given by the
SUBDIRS variables of all Makefiles need to walk libraries in dependency
order.

I'm not sure whether it's worth actually trying to fix any of these
issues except maybe the relative ordering between different variables
in one Makefile.am.

Cheers,
Ralf
