[R] problem loading rgdal with Rapache, problem solved due to libexpat with apache.

[Roger Bivand]

You should provide at least the output of sessionInfo() and the messages
issued by rgdal on load. rgdal has recently been updated to try to address
issues of interference between applications, and it would help very much to
know your intentions, platform, and the versions of the software you are
using.
