>Description:

 I am using the AX_BOOST_FILESYSTEM and AX_BOOST_UNIT_TEST_FRAMEWORK macros found in the autoconf-archive package. I have also installed boost itself from a package:

 pkg_add -r boost-all autoconf-archive

 I am using a very simple configure.ac that tests for Boost like:

..
AX_BOOST_BASE
AX_BOOST_SYSTEM
AX_BOOST_FILESYSTEM
AX_BOOST_THREAD
AX_BOOST_UNIT_TEST_FRAMEWORK
..

 When I run configure I get:

....
checking whether the Boost::System library is available... yes
checking whether the Boost::Filesystem library is available... yes
configure: error: Could not link against  !

However, I have successfully compiled and linked a program which uses the filesystem library. I have tried with the options provided by the configure:
./configure  --with-boost-filesystem=boost_filesystem --with-boost-unit-test-framework=boost-unit-test-framework

and then I get:

..
checking whether the Boost::System library is available... yes
checking whether the Boost::Filesystem library is available... yes
checking for exit in -lboost_filesystem... yes
checking whether the Boost::Thread library is available... yes
checking for exit in -lboost_thread... yes
checking whether the Boost::Unit_Test_Framework library is available... yes
configure: error: Could not link against boost-unit-test-framework !

So now it seems like Boost::Filesystem is properly found, but Boost::Unit_Test_Framework cannot be linked.
This behaviour is rather odd. I would just expect ./configure to work out of the box, and generate properly the  $(BOOST_CPPFLAGS), $(BOOST_FILESYSTEM_LIB) and $(BOOST_UNIT_TEST_FRAMEWORK_LIB) variables.

 I have tried exactly the same in several Linux distributions and it works fine.
 I have created a very small test case to show the problem, please see "How to repeat the problem"


 The versions of the packages I use:
autoconf-2.62
autoconf-wrapper-20071109
autoconf-archive-0.2009.04.19
automake-1.10.1
automake-wrapper-20071109
boost-all-1.43.0


>How-To-Repeat:

 1. Create a file configure.ac:
AC_INIT([Package],[0.1],[user at com],[pack])
AC_CONFIG_SRCDIR([Makefile.am])
AM_INIT_AUTOMAKE
AC_PROG_CXX
# Checks for boost libraries (the macros are found in the autoconf archive)
AX_BOOST_BASE
AX_BOOST_SYSTEM
AX_BOOST_FILESYSTEM
AX_BOOST_THREAD
AX_BOOST_UNIT_TEST_FRAMEWORK
AC_CONFIG_FILES([Makefile])
AC_OUTPUT

 2. Create a simple Makefile.am file:
AUTOMAKE_OPTIONS = 1.8 foreign

 3. Run autoreconf:
# autoreconf -i -f

 4. Run configure:
# ./configure

 5. Check the error reported:
checking whether the Boost::System library is available... yes
checking whether the Boost::Filesystem library is available... yes
configure: error: Could not link against  !
