Bug Report for nMap-3.28

[Don't Ask]

To whom it may concern,

Please forgive my ignorance because I'm very new to the "*nix" environment. 
Below is a warning that I received 3 times after typing "./configure" while 
trying to install nmap-3.28 on FreeBSD 5.1(i386). I'm not sure what other 
information you may need. My email address for further info is in 
"address@hidden".

configure: WARNING: netinet/if_ether.h: present but cannot be compiled
configure: WARNING: netinet/if_ether.h: check for missing prerequisite headers?
configure: WARNING: netinet/if_ether.h: proceeding with the preprocessor's 
result
