----------------------------------------------------------+-----------------
 When compiling and running lftp on Leopard it causes the 'known' 100% cpu
 usage. This however is not entirely related to the 'poll' bug, like in
 Tiger.

 I have attached a patch for configure that detects the broken poll on
 Leopard as well.
 And a modification to the Portfile that sets the
 MACOSX_DEPLOYMENT_TARGET=10.4, which fixes the cpu usage issue on Leopard.
