Again, I'm pretty far from a linking expert, but I can't say I'm convinced
that the dependant libraries also need to be linked, unless functions from
these dependencies are used by raster2pgsql. Mapserver used to use
--dep-libs, but found the linking unnecessary and removed this feature:
http://trac.osgeo.org/mapserver/changeset/11618

I suspect --dep-libs is not needed with shared libraries of GDAL, e.g. ldd
libgdal.so will show it is already linked with its dependants at runtime,
thus shouldn't need any further linking. However, I'm not sure if
statically linked libraries should be considered differently.
