net-analyzer/wireshark-1.4.4 does not compile with net-dns/c-ares-1.6.0 (does work with 1.7.4) unfortunately portage did of course overwrite the error log now but I *think* it failed at configure
Thank you for report! net-dns/c-ares-1.6.0 was dropped from the tree one year ago and net-analyzer/wireshark-1.4.4 build successfully with currently stable c-ares-1.5.3.
