I am trying to set up my Fedora Core 4 box to run an XSUB I developed that serves as an SQL interface to the mdbtools libraries. This works on my old FC2 machine fine, but when I try to install it here the "perl Makefile.PL" complains about not being able to find the libraries needed. Makefile.PL looks like: 
use 5.008003;
use ExtUtils::MakeMaker;
# See lib/ExtUtils/MakeMaker.pm for details of how to influence
# the contents of the Makefile that is written.
WriteMakefile(
    NAME              => 'MdbSQL',
    VERSION_FROM      => 'lib/MdbSQL.pm', # finds $VERSION
    PREREQ_PM         => {}, # e.g., Module::Name => 1.1
    ($] >= 5.005 ?     ## Add these new keywords supported since 5.005
      (ABSTRACT_FROM  => 'lib/MdbSQL.pm', # retrieve abstract from mod
+ule
       AUTHOR         => 'Jon Dixon <dixonj@localdomain>') : ()),
#    LIBS              => ['-L/usr/local/lib ', `pkg-config --libs gli
+b-2.0 `, '-L/usr/lib '], # e.g., '-lm'
    LIBS              => ['-L/usr/local/lib ', '-lmdb -lmdbsql ', `pkg
+-config --libs glib-2.0 `, '-L/usr/lib '], # e.g., '-lm'
    DEFINE            => '', # e.g., '-DHAVE_SOMETHING'
    INC               => '-I. -I/usr/local/include ' . `pkg-config --c
+flags glib-2.0 `, # e.g., '-I. -I/usr/include/other'
        # Un-comment this if you add C files to link with later:
    # OBJECT            => '$(O_FILES)', # link all the C files too
);
if  (eval {require ExtUtils::Constant; 1}) {
  # If you edit these definitions to change the constants used by this
+ module,
  # you will need to use the generated const-c.inc and const-xs.inc
  # files to replace their "fallback" counterparts before distributing
+ your
  # changes.
  my @names = (qw());
  ExtUtils::Constant::WriteConstants(
                                     NAME         => 'MdbSQL',
                                     NAMES        => \@names,
                                     DEFAULT_TYPE => 'IV',
                                     C_FILE       => 'const-c.inc',
                                     XS_FILE      => 'const-xs.inc',
                                  );

}
else {
  use File::Copy;
  use File::Spec;
  foreach my $file ('const-c.inc', 'const-xs.inc') {
    my $fallback = File::Spec->catfile('fallback', $file);
    copy ($fallback, $file) or die "Can't copy $fallback to $file: $!"
+;
  }
}

Running this gives: 
Note (probably harmless): No library found for -lmdb
Note (probably harmless): No library found for -lmdbsql
Writing Makefile for MdbSQL

[download]
The libmdb.so and libmdbsql.so libraries are installed in /usr/local/lib, with header files in /usr/local/include. If I go in and try to manually add the -lmdb and -lmdbsql on EXTRALIBS and LDLOADLIBS in the Makefile, the "make" process works fine but I get an error in "make test" as soon as it tries to load a function from the libmdbsql.so.

Anyone have suggestions for what is needed to allow Makefile.PL to be able to find the proper libraries?

Thanks, Jon
