[Rd] rgeos on Linux requires GEOS 3.2.3, not 3.3.1

[Dan Bebber]

Some notes on installing rgeos in R 2.14.0 on a Linux Mint 11 (x86_64-pc-linux-gnu) machine
1. rgeos 0.1-15 will not run with GEOS 3.2.0-1, which is the version currently available on Synaptic package manager
2. I installed GEOS 3.3.1 (the latest version) from http://trac.osgeo.org/geos/, but rgeos will not run with this either
3. I then install GEOS 3.2.3, and now rgeos works fine!

It seems therefore that there is a mismatch between the GEOS version that is available on Synaptic, and the rgeos version on Cran (just in case anyone else comes across this issue).

Best wishes,
