ok, noting unusual so far.

I did not mean to imply that this discussion should be reopened, just 
that some people might be a little surprised that a "minor" bug fix 
breaks their code :)

Still, MPL claims that png isn't supported. If this is a Cython issue 
somewhat color me surprised.

Ok. 3.4.1 shipped with the new clisp 2.47 which has been working out 
rather well, but there is always a compiler that breaks it. Sage 4.0 
will switch to ecl and use Maxima a whole lot less. Eventually Maxima 
won't be used for anything in Sage, but that is still some time to go.

If downgrading to the old cython does not fix your problem I am more 
than happy to look into install.log from your box to see if I can find 
the cause for the MPL png issue for example.

Cheers,
