[gdal-dev] recent change?, issue with OGRGeometryFactory in R

[Michael Sumner]

I figured it out, I'd moved to from-source builds to /usr on a machine that
had apt installs to /usr/local so the stale headers were in the way.

A good lesson for me (don't do what I'm doing it's fraught haha) and just a
note to clear the air.

Cheers, Mike
