+Subject: [PATCH 1/1] Set TTF_DIR to the Gentoo corefonts location.
+
+The default value of TTF_DIR in jpg-config.inc.php points to
+/usr/share/fonts/truetype, a location that does not exist on
+Gentoo. Since JpGraph largely only supports the Microsoft
+corefonts, we point it to /usr/share/fonts/corefonts instead.
+If the user does not have the corefonts installed, this is no
+great loss: neither location exists.
