Problems compiling nmap3.50 on SuSE 9.0

Hello. Anyone been able to compile nmap 3.50 from source on SuSE 9.0 ? Due to the problems we're having getting the provided nmap 3.30 to work properly due to a broken kernel, I thought I'd try the latest version to see if it would work any better. When I do ./configure, the script errors out with: checking for type of 6th argument to recvfrom()... configure: error: Cannot find type for 6th arguement to recvfrom() I have found a bunch of references to the same error on Google, but no answers as to how to fix it. Can anyone here help me out ? Thanks, Stuart.
