Darwin: interlib deps

[Akim Demaille]

I'm not sure I understand how interlib deps are expected to work.
In a project of mine, I have several directories containing
libs.  For instance, in the ast/ directory I have the following
Makefile.am snippet:

noinst_LTLIBRARIES = libast.la
libast_la_SOURCES =                                     \
        position.hh location.hh                         \
        ...
        libast.hh libast.hxx libast.cc                  \
        tasks.hh tasks.cc

and to have interlib dependency support, I report that this
lib depends on three siblings: symbol, task, and misc:

libast_la_LDFLAGS = -L../symbol -lsymbol -L../task -ltask -L../misc 
-lmisc

It seems that linking is correct:

/bin/sh ../../libtool --tag=CXX --mode=link g++ -Wall -W -Wcast-align 
-Wcast-qual -Wformat -Wmissing-prototypes -Wshadow -Wstrict-prototypes 
-Wwrite-strings -g -O2 -pipe   -o libast.la  -L../symbol -lsymbol 
-L../task -ltask -L../misc -lmisc decs.lo arrayexp.lo arrayty.lo

.libs/tasks.oranlib .libs/libast.acreating libast.la(cd .libs && rm -f 
libast.la && ln -s ../libast.la libast.la)

in the beginning -L../symbol -lsymbol -L../task -ltask -L../misc -lmisc 
do appear.
But when I try to link a small test case:

check_PROGRAMS = test-ast
test_ast_SOURCES = test-ast.cc
test_ast_LDADD = libast.la
TESTS = test-ast

I have linking failures: neither symbol, task or misc is added.
libast.la contains:

# Libraries that this one depends upon.
dependency_libs=' -L/Users/akim/src/tc/_build/src/symbol 
-L/Users/akim/src/tc/_build/src/task 
-L/Users/akim/src/tc/_build/src/misc   '

is this normal?  When I had -lsymbol etc. by hand, linking and execution
passes.

How am I expected to do that?

If I try to link again libast as a dynamic library it fails to:

/bin/sh ../../libtool --tag=CXX --mode=link g++ -Wall -W -Wcast-align 
-Wcast-qual -Wformat -Wmissing-prototypes -Wshadow -Wstrict-prototypes

-last appears, but...
