Jorge, WriteArray() needs the gdal-numpy module to be built. So ensure you have numpy and numpy-devel packages installed (or whatever they are named on your distro) when rebuilding the GDAL python bindings. I guess you lack the numpy-devel package that is necessary for building and probably not installed if you've just installed the packaged version.
