Невозможно установить библиотеки rgdal и rgeos R в Red Hat Linux

У меня возникла ошибка при компиляции пакета rgdal adn rgoes на нашей Linux-машине с RedHat. Я попытался провести некоторое исследование, но не смог найти возможного решения. Не могли бы вы помочь мне с этим, так как это очень важно для меня, чтобы решить.

If you have installed the GDAL libraries, then make sure that
gdal-config is in your path. Try typing gdal-config at a
shell prompt and see if it runs. If not, use:
--configure-args='--with-gdal-config=/usr/local/bin/gdal-config'
with appropriate values for your installation.
