[R-sig-Geo] sp 0.9-61

[Roger Bivand]

A update to the sp package, version 0.9-61 has been released on CRAN and 
will propagate to mirrors soon.

Versions 0.9-56 through 0.9-60 can be installed on R < 2.9.1 but fail when 
functions calling anyDuplicated() (spChFIDs() or any function calling 
Polygons()) are used. The problem only affects users of R < 2.9.1 and sp 
between 0.9-56 and 0.9-60. Users of R < 2.9.1 should revert to 0.9-52, or 
upgrade R if this problem affects you.

The new version now correctly depends on versions of R >= 2.9.1 that 
provide anyDuplicated().
