Bug#973351: cypari2 need an update for pari-2.13

[Bill Allombert]

Source: cypari2
Version: 2.1.1-2
Severity: important
Tags: patch

Dear Debian Science Team,

cypari2 need an update to be compatible with 
pari 2.13.0 (in experimental) which will be uploded to sid soon.

The fix needed is simple however the doctests are very fragile
(they depend on unspecified behaviors) and need to be updated (for
example they depend on the documentation of some functions).

The patch does not attempt to deal with the doctests failure.

Cheers,
