Just a normal build: but a strange configure error did occur.
$$$
checking whether we are using the GNU C++ compiler... yes checking whether g++ accepts -g... yes checking dependency style of g++... gcc3 configure: error: No C++ compiler not found. Please install a C++ compiler.

I found it's just a ``which`` in configure.in.

# check for C++ compiler explicitly and fail if none is found, do this check # after AC_PROG_CXX has set the CXX environment variable which $CXX >/dev/null 2>&1 if test "x$?" != "x0"; then AC_MSG_ERROR([No C++ compiler not found. Please install a C++ compiler.]) fi

I didn't know that the ``which`` utility was considered a compiler. :p
How about just using a shell builtin, ``hash``, ``type -P`` or just ``eval $CXX --version`` as a test instead?
