update M4RI to newest upstream release

[malb]

A new version of M4RI is available: ​20121224

• it improves performance
• compilation time is considerably shorter because cache tuning was dropped

Install: ​http://sage.math.washington.edu/home/malb/spkgs/libm4ri-20121224.spkg

So where's the spkg? ;-)

[malb]

Working on it, I needed a ticket number for SPKG.txt

Ah, zu Weihnachten 'ne Zeitmaschine bekommen und gleich mal drei Tage zurückgereist.

Hat der Weltuntergang also nicht stattgefunden?

It only works for M4RI releases though.

We should probably add -L{SAGE_LOCAL}/lib to LDFLAGS, or set (PNG_CFLAGS and) PNG_LIBS [on Darwin [if pkg-config isn't installed or functional]]; cf. David Joyner's report for Sage 5.7.rc0 on sage-release.

cf. David Joyner's report for Sage 5.7.rc0 on sage-release.

I had less luck on 10.8.2 (2.66 GHz Intel Core 2 Duo):

Hmmm, doesn't look like libm4ri['s spkg-install] was the culprit though:
