If we allow an UTF-8 banner then we may also allow UTF-8 string representations for Sage objects (why not?). But I think we do not want to force the user to have UTF-8 output because it is always harder to parse an UTF-8 string than an ASCII string (this argument is also valid for the Sage

Actually, the version of libpng the compiler should use is not the one which you just installed but the one which is shipped with sage (ie $SAGE_ROOT/local/lib/libpng*)... It looks like a problem of compiler options but I have no clue of how to solve this and it is quite strange that it fails
