Configuration failed to find one of freetype2 libpng libtiff-4 libjpeg. Try installing:
* deb: libfreetype6-dev libpng-dev libtiff5-dev libjpeg-dev (Debian, Ubuntu, etc)
* rpm: freetype-devel libpng-devel libtiff-devel libjpeg-turbo-devel (Fedora, CentOS, RHEL)
* csw: libfreetype_dev libpng16_dev libtiff_dev libjpeg_dev (Solaris)
If freetype2 libpng libtiff-4 libjpeg is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a freetype2 libpng libtiff-4 libjpeg.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
