$ pkg-config --libs libmodplug
-L/Volumes/ffmpeg_compile/lib -lmodplug

So either -lstdc++ or -lc++ don't appear in the command output.  

I checked libmodplug.pc.  

$ cat /Volumes/ffmpeg_compile/lib/pkgconfig/libmodplug.pc 
prefix=/Volumes/ffmpeg_compile
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: libmodplug
Description: The ModPlug mod file playing library.
Version: 0.8.8.5
Requires: 
Libs: -L${libdir} -lmodplug
Libs.private: -lstdc++ -lm
Cflags: -I${includedir}

-lstdc++ appears in Libs.private: line.  But even though configure with "./configure --pkg-config-flags=--static --enable-libmodplug", the result is same error.
