===== backport el paquete si no lo esta =====

First, check for a backport on <debian-backports>.  If unavailable:

1) Add a deb-src line for sid (not a deb line!); ask me about <deb-src sid> 

2) enable debian-backports (see <bdo>) 

3) 
<code>
aptitude update; aptitude install build-essential; aptitude build-dep packagename; apt-get -b source packagename
</code>

4) install the resultant debs.  To change compilation options, see <package recompile>; for versions newer than sid see <uupdate>.
