I've had exactly this same issue, except that I'm using Parallels  
instead of VMWare. In my case, Parallels creates two interfaces, en2  
and en3, in addition to the system's en0, en1 and fw0 for a total of  
five interfaces. The problem is that Mac OS X only has 4 bpf devices  
and there is no way to create more. So when nmap tries to open the  
fifth interface, in my case fw0, it fails. I think your patch is the  
best option; this way at least the first 4 interfaces will be used  
and the rest ignored.

Incidentally, nmap mysteriously started working again on my system. I  
_think_ it's because I installed the latest beta of Parallels which  
must be handling networking differently. So it may be possible that  
VMWare will eventually fix it as well. Unfortunately, this means I  
can no longer test the patch. :)
