The reason for the build failure on Snow Leopard is that although the Xcode clang compiler collection is being used, on Xcode 3 there is no clang++ compiler to handle C++ code, therefore the Xcode clang compiler collection uses llvm-g++-4.2 as the C++ compiler on Xcode 3.

The solution is to blacklist those versions of clang by adding "{clang < 137}" to the compiler.blacklist.

You've already done this! But it is not having any effect because you have forgotten to add the line "PortGroup compiler_blacklist_version 1.0" to the top of the portfile. It is the compiler_blacklist_versions portgroup that knows how to blacklist only specific versions of compilers; MacPorts base itself only knows how to blacklist compilers by name.
