Ok I have figured out what is causing the problem.  I have libdl.so 
available so in the modules.c file 

#if defined(HAVE_DLFCN_H)                                /* Linux, BSD, 
Hurd */
#   include <dlfcn.h>                        /* dlopen(), dlsym(), 
dlclose() */
#   define HAVE_DYNAMIC_PLUGINS
#elif defined(HAVE_IMAGE_H)                                          /*
 BeOS */
#   include <image.h>
#   define HAVE_DYNAMIC_PLUGINS
#elif defined(WIN32)
#   define HAVE_DYNAMIC_PLUGINS
#else
#   undef HAVE_DYNAMIC_PLUGINS
#endif

dlfcn.h is included and image.h not.  However in the modules_plugin.h  
#ifdef SYS_BEOS
    *handle = load_add_on( psz_filename );
    return( *handle < 0 );

#elif defined(WIN32)
    *handle = LoadLibrary( psz_filename );
    return( *handle == NULL ); 

#elif defined(RTLD_NOW)

the test is on SYS_BEOS.  

These tests should be consistant.  If we HAVE_DLFCN_H then we should 
use that test in modules_plugin.h to provide a consistant view.
