6.49BETA1 configure failure

[ohauer]

I tested a nmap-6.49BETA1 build in an isolated build jail (FreeBSD pouderie).

The following configure arg will fail
--with-openssl=/usr --without-localdirs --without-zenmap --without-ndiff --with-libpcre=/usr/local --with-liblua=included --without-nmap-update --prefix=/usr/local
...
checking if AF_INET6 IPPROTO_RAW sockets include the packet header... no
checking for a Python interpreter with version >= 2.4... none
configure: error: in /wrkdirs/usr/ports/security/nmap/work/nmap-6.49BETA1': configure: error: --with-ndiff requires Python 2.x with x>=4 Seeconfig.log' for more details
===> Script "configure" failed unexpectedly.

6.47 builds fine, it seems the culprit comes from the changes in configure.ac to test if python is available and if not ignore --without-ndiff.

@G10h4ck Looks like a good approach. Change the condition to elif ... fi instead of else if ... fi fi and commit it. Thanks!

Thanks, changing s/else/elif/ fixed fixed the the issue fir me.
Will push BETA1 on the weekend into the FreeBSD ports tree so it gets wider testing
