It is strange that I get neither the error nor the warnings with clang-3.4-r100, although for testing, I explicitly specified -Wformat-security in CXXFLAGS. Error and warnings should be fixed in current git master of eix (>=eix-0.30.2) on BerliOS and GitHub (live ebuild is in the mv overlay)
Unfortunately, I'm getting the same thing from the newly in-tree six-0.30.2: clang++ -DHAVE_CONFIG_H -I. -I.. -I/opt/gentoo/usr/include -DSYSCONFDIR=\"/opt/gentoo/etc\" -DLOCALEDIR=\"/opt/gentoo/usr/share/locale\" -std=gnu++1y -std=gnu++1y -arch x86_64 -march=core-avx-i -mmacosx-version-min=10.9 -O0 -g -pipe -c -o cache/common/assign_reader.o cache/common/assign_reader.cc cache/common/assign_reader.cc:53:33: error: invalid operands to binary expression ('basic_istream<char, std::__1::char_traits<char> >' and 'nullptr_t') while(likely(getline(is, lbuf) != NULLPTR)) { ~~~~~~~~~~~~~~~~~ ^ ~~~~~~~ ./eixTk/likely.h:14:37: note: expanded from macro 'likely' #define likely(x) __builtin_expect((x), 1) ^ 1 error generated.

Thanks for the second report: This is a different occassion than the first reported, and so I did not find it. (As mentioned: my clang version does not spit an error for this...). A grep shows that this is the last occassion with getline() in the code. In a few hours, I will have time to fix the issue and will commit it to the git repositories on BerliOS and GitHub. If you find time for testing the live ebuild, it would be nice if you could report back whether it works for you.
Ah - I hadn't spotted that! I'll try to build the live ebuild over the weekend, and let you know how it goes. On the same system, eix built with gcc is fine and is what I'm currently using.

Sorry for the delay - built six-99999999 from the 'mv' overlay (at change a6aff014ae0f5817c9a697ca2b2dfbd102ccec67), and it installed correctly with clang-3.4.1 (and gcc too).
Closing since this is fixed in 0.30.3
