This page appears to be written by someone without sufficient insight into 
basic Linux handling of shared objects, and without understanding the need 
to clarify and simplify. There is no need to install most of the drivers 
suggested, there is no need to build and install GDAL with all the flags 
given, there is no need to put it in a special /opt location, there is no 
need to build from trunk.

However, given that you've followed these arcane instructions, did you add 
the install location to a directory under /etc/ld.so.conf.d as root, then 
run /sbin/ldconfig to make the shared objects stored there available?

The page does use LD_LIBRARY_PATH, and does run ldconfig from time to 
time, but the page is far too picky.

Also consult:

https://r-forge.r-project.org/scm/viewvc.php/pkg/inst/README?view=markup&root=rgdal

or inst/README in the rgdal TARBALL for accumulated installation hints.

Hope this clarifies,

Roger
