#59890: py-graph-tool has wrong condition for deciding when to use sparsehash
------------------------+---------------------------
 Reporter:  ryandesign  |      Owner:  count0

 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.6.2
 Keywords:              |       Port:  py-graph-tool
------------------------+---------------------------
 The py-graph-tool Portfile has this code:

 {{{
     # Clang uses the old libstc++ from gcc 4.2 before OS X 10.9. Boost
 doesn't
     # include some of the tr1 headers in libstdc++ and defines its own tr1
     # classes. This causes conflicts with sparsehash which insists on
 using
     # the old tr1 headers.
     if {[string match *gcc* ${configure.compiler}] ||
         ${os.major} >= 13 && ${os.platform} eq "darwin"} {
         depends_lib-append port:sparsehash
     } else {
         configure.args-append --disable-sparsehash
     }
 }}}

 This is out of date. As of MacPorts 2.6.0, libc++ is used by default on
 10.6 and up. But you should not infer the C++ standard library based on
 the OS version. Instead, you should check `${configure.cxx_stdlib}` if you
 need to make a decision based on the C++ standard library.
