Hmm, I don't have this problem. Though I have 10.7 and I don't remember
how my `convert` was installed, but anyway
$ which convert
/usr/local/bin/convert
Is it possible that convert isn't installed correctly? In the code for
animate?? I see you might want to try
from sage.misc.sage_ostools import have_program
have_convert = have_program('convert')
and see whether Sage is finding it.
You could also install ffmpeg, though I agree that you don't want to have
to do that. Let us know what happens - maybe some other people on 10.9 can
try to replicate this.
