[R-sig-Geo] Problem installing rgeos

[chris english]

Scott:

I found this discussion that chokes at the same point as yours on:
http://unix.stackexchange.com/questions/50151/getting-newer-version-of-geos-than-what-is-available-in-debian-repositories

I don't know that it will be applicable. Why don't you post your
sessionInfo() as this may be useful to others in the future.  Which version
of GEOS do you have installed?
