Re: [sage-support] is_polynomial with symbolic coefficient returns wrong answer ? Bug ?
Hello,
this is certainly a bug. The error comes from (a/s**2).is_polynomial(s).

sage: s, a, b= var('s a b')
sage: (1/s^2 + s).is_polynomial(s)
False
sage: (a/s^2 + b*s).is_polynomial(s)
True
sage: version()
'Sage Version 5.6, Release Date: 2013-01-21'
sage:
should return False ?

[sage-support] Should freetype be updated in Sage?
Trying to run `runsnake` from within sage commandline fails on my Fedora 19 system. `runsnake` on my system requires that `libfreetype` define symbol `FT_Face_GetCharVariantIndex` which started in `freetype` version 2.3.6. Currently Sage is distributed with `freetype` version 2.3.5. Fedora 19 is distributed with `freetype` version 2.4.11. Perhaps Sage could update its version of freetype and/or use the host system's freetype library? -- You received this message because you are subscribed to the Google Groups sage-support group.
