Comment (by mojca):

 No, we should fix this properly rather than let users patch files
 manually.

 I can imagine that this is a problem since I already had problems building
 wxWidgets-3.0 and had to add the following:
 {{{
 #!tcl
 if {[string match *clang* ${configure.cxx}]} {
     configure.ldflags-append \
                     -stdlib=${configure.cxx_stdlib}
 }
 }}}
 The main question is how to fix this properly and whether there is any way
 to submit this upstream / ask upstream to fix it. I reported the initial
 problem to wxWidgets developers, but they argued that whatever MacPorts is
 already setting is not sufficient.
