Comment (by ken.cunningham.webuse@…):

 perhaps a thing to try on 10.5 PPC is to edit this block in the Portfile
 {{{

 # blacklist compilers that do not support C11 (redefinition of typedef
 ‘GdkX11Monitor’ at gdkscreen-x11.h:33)

 if {[variant_isset quartz]} {
     compiler.blacklist  *gcc* {clang < 425}
 } else {
     compiler.blacklist  *gcc* {clang < 300}
 }
 }}}

 re-enable gcc, and try a newer gcc that supports C11 -- most of which
 build on Tiger PPC and so probably build on Leopard PPC.
