${PREFIX}/include is more correct for FreeBSD.  PREFIX is a make(1)  
variable, however, and I don't know how that info gets easily passed  
to mkmf.  I think you could probably do something like:

incpath = (path + ENV['PATH']).flatten.collect{|dir|  
File.expand_path(File.join(File.expand_path(dir), '../include')))}

I'm not wild about including the ENV['PATH'] bit (security), but the  
rest should nab most corner cases for users.  -sc
