The newly stabalized nmap 6.01 ebuild requires ipv6 support even though my global system flags have ipv6 disabled. The ebuild should check if the ipv6 is enabled, and then configure the package appropriately. Reproducible: Always Steps to Reproduce: 1. Disable ipv6 flag in /etc/make.conf 2. Re-emerge libpcap without the ipv6 flag enabled. 3. Emerge the new 6.01 ebuild for nmap. Actual Results: Emerge aborts, asking for ipv6 to be enabled for libpcap. Expected Results: Emerge should configure nmap to not use ipv6 and finish the emerge successfully.
I guess bug #417759 was fixed a bit carelessly. I have added IUSE=ipv6 now. Thanks for the report.
