I think I found the problem with the "incompatible" plugin...

olsrd_plugin_init() says

* Return     : fail (0) or success (1)

but your InitOBAMP() function was returning 0 if it was working. I know, the 
"0 = fail, 1 = success" encoding is insane (that's why I changed it in plugin 
version 6), but I built in a "compatiblity layer" for the old system.

I just don't know why your plugin ever worked with this return value, because 
the corresponding old plugin loader code said:

/* Initialize the plugin */
  if (init_olsr_plugin(plugin) != 0) {
    const int save_errno = errno;
    errno = save_errno;
    OLSR_ERROR(LOG_PLUGINS, "---------- LIBRARY %s FAILED ----------\n\n", 
    return -1;

So, it should have failed...

Do you have an idea what happend ?
