Comment(by shiena.jp@…):

 How about librsvg's rsvg-convert?
 It was possible to convert it into non-square icon.
 {{{
 depends_build       port:librsvg \
                     port:makeicns
 platform darwin {
     set appname {TortoiseHg}
     post-extract {
         copy ${filespath}/${appname}.in ${workpath}/${appname}
         system "rsvg-convert ${worksrcpath}/icons/svg/thg_logo.svg \
             --format=png \
             --width=512 \
             --height=512 \
             --output=${workpath}/${appname}.png"
         system "makeicns -in ${workpath}/${appname}.png \
             -out ${workpath}/${appname}.icns"
     }
 }
 }}}
