This is off-topic here - the topic here is space-time data.

Your question is answered with respect to Personal geodatabases on the 
Windows platform in thread:

http://article.gmane.org/gmane.comp.lang.r.geo/13571

(link to gmane because it crosses a month boundary). You did join that 
thread, and said there that you are using OSX. You were able to open Pgeo 
files, I think. Are you thinking of the new file geodatabase format? If 
you read:

http://www.gdal.org/ogr/drv_filegdb.html

you will see that you must build GDAL linking to the proprietary FileGDB 
API SDK, which requires an ESRI global account. Reading the OGR format 
file would tell you that, no?
