R packages here are installed in /usr, not /usr/local/. Most of the time when I run 'update.packages()' each finds headers in /usr/include. Today, the package 'rgl' failed to build because it was looking for freetype.h in /usr/local/include/freetype2/.
By making a softlink from /usr/include/freetype2 to /usr/local/include/ the package update built without further error. For future reference, if an update attempt fails because the code is looking in a different directory than where the required file (usually a header) is found, is there a way to specify the correct directory when issuing the update.packages() command?
