The releases are synched such that the numpy version is "twice" (by an 
idiosyncratic form of arithmetic) that of the scipy version. numpy 0.9.8 <-> 
scipy 0.4.9 .

The latest SVN revisions should match (it's a bug, otherwise). numpy 2761 is 
recent enough that an SVN checkout of scipy will probably be fine.
