If you're trying to use the Clang C++ compiler on Maverick and you're getting link failures like
undefined reference to `std::basic_streambuf<char, std::char_traits<char> >::seekoff(long, std::_Ios_Seekdir, std::_Ios_Openmode)you're just going to have to patch it and build it yourself. It's actually pretty easy, it just takes a few minutes.
// Ubuntu 10.10 "Maverick Meerkat" -- gcc-4.4.5 AddGnuCPlusPlusIncludePaths("/usr/include/c++/4.4", "i686-linux-gnu", "", "64", triple);
With any luck Clang will be patched up in pretty short order, thus rendering this a historical curiosity.
