Purging chroot-autobuild/build/buildd/predict-2.2.3

[John Nogatch (jnogatch)]

The attached patch moves "-lm" later in several "cc" commands, so that the missing math routines are found in the library.

This problem has been reported upstream as: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=630418

[Launchpad Janitor (janitor)]

This bug was fixed in the package predict - 2.2.3-3ubuntu2

---------------
predict (2.2.3-3ubuntu2) oneiric; urgency=low

  * debian/rules: move -lm later in cc command to fix geosat, et al.
