Comment (by braumann@…):

 Thank you for pointing me to http://llvm.org/bugs/show_bug.cgi?id=22270

 Looking inside the Portfile
 http://trac.macports.org/browser/trunk/dports/www/webkit-
 gtk-2.0/Portfile?rev=120881 I suddenly found the lines

 {{{
     if {${os.major} < 10} {
                 depends_build-append      port:python27
                 # https://trac.macports.org/ticket/35793
                 configure.python          ${prefix}/bin/python2.7

                 # https://trac.macports.org/ticket/38682
                 configure.optflags-append -fno-blocks
             }
 }}}

 Since {{{gcc-4.9}}} has no and does not need a {{{-fno-blocks}}} switch,
 once I commented that line the configuration of {{{webkit-gtk3-2}}}
 worked:

 {{{

 }}}

 However, after issuing

 {{{
 $ sudo port install webkit-gtk3-2.0 configure.compiler=macports-gcc-4.9
 }}}

 and compiling, after a while I had to surrender, since {{{webkit-
 gtk3-2.0}}} contains code which is not supporting PPC:

 {{{

 }}}

 To summarize, {{{webkit-gtk3-2.0}}} unfortunately cannot be built on
 10.5.8 PPC, but not because of existing {{{clang}}} deficiencies, just
 since {{{Macroassembler}}} only supports ARM, ARMv7, MIPS, x86, x86_64,
 and SH4.
