 Thank you, your suggestion worked to resolve the issue.

 P. S. Will any Macports clang assembler work with `libstdc++` (for Intel,
 obviously)?

 (On a side note, this is potentially a problematic solution, since some
 ports will build without errors but produce broken binaries: having
 assembler recognizing AVX, for example, will not make CoreDuo to support
 them. GCC at least honestly fails at compile time.)
