 Hi, I'm installing Macports over AFS (Apple File System). One thing I've
 found while installing many of the ports is that hard links don't work on
 AFS while many ports use them to set locks (libtool), or link the regular
 executable name (python) to a specific version (python26).

 So while I've been installing these I've had to modify the Makefiles by
 hand, changing all of the ln's to "ln -s" so the port won't fail with an
 error, or hang while trying to acquire a non-existent lock.

 It might be worth detecting AFS in the Port system and then changing all
 links to symbolic in that case, considering most times there is already an
 $(LN) variable in the makefile.
