Thanks for this! With Howard's patch #229 seems OK, and other issues seem OK
in current R package rgdal (like the exposure of how to look for installed
metadata files).

One oblique question - could there be any way of adding support to reveal
the EPSG version from within PROJ.4? A short fix for now would be to add an
epsg_version.txt or *.aux to nad/, and later find a way to access and reveal
its contents. The current R advice is:

NEWS <- "http://svn.osgeo.org/metacrs/proj/trunk/proj/NEWS"
PROJ4_NEWS <- readLines(url(NEWS))
lns <- grep("Release Notes|EPSG", PROJ4_NEWS)

to give some guidance, but if there was a epsg_version.txt centrally
maintained, updated and distributed, everyone could record in their work
which version of EPSG they were using. Probably this applies to other
metadata files too. Just an idea for something needed for reproducible research.

Best wishes,
