Comment (by devans@…):

 Apple clang 3.0 was introduced in Xcode 4.2.  Earlier versions of clang
 are often found to be problematic and can be blacklisted by version using
 the compiler_blacklist_versions portgroup
 {{{
 PortGroup compiler_blacklist_versions 1.0
 ...
 compiler.blacklist  *llvm-gcc-4.2 {clang < 300}
 }}}

 or such depending on what testing with earlier Xcode versions reveals.

 See XcodeVersionInfo for details of what compilers are available by OS X
 and Xcode version.

 Which compilers are selected after black listing is determined by
 compiler.fallback, the default values of which are set based on Xcode
 version.  See code in
 [https://trac.macports.org/browser/trunk/base/src/port1.0/portconfigure.tcl
 base/src/port1.0/portconfigure.tcl] for details.
