What does:

$ gdalinfo --version
GDAL 1.2.6.0, released 2005/03/13

report for you? I do not think you have installed GDAL properly, my ldd on 
rgdal.so lists libgdal.so and its (many) dependencies, these are missing 
for you (the dependency on R is not at all necessary):

$ ldd /home/rsb/topics/Ris210/lib/R/library/rgdal/libs/rgdal.
so
        libgdal.so.1 => /usr/local/lib/libgdal.so.1 (0x003f0000)

        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x00935000)
        libpng12.so.0 => /usr/lib/libpng12.so.0 (0x00251000)

        libpthread.so.0 => /lib/tls/libpthread.so.0 (0x00274000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x0072e000)

        libnsl.so.1 => /lib/libnsl.so.1 (0x00c92000)
        libgssapi_krb5.so.2 => /usr/kerberos/lib/libgssapi_krb5.so.2 (0x00d10000)
        libcom_err.so.3 => /usr/kerberos/lib/libcom_err.so.3 (0x002ca000)

It is almost never a good idea to install binary on Linux, almost always a 
good idea to install GDAL from source, then install rgdal from source, 
which is simple:

> install.packages("rgdal")

which then makes sure that all the bits and pieces are lined up correctly.

Please let the list know if this helps.
