How can I fix this error - “cc1: error: invalid option ‘tune=opteron’”¶

How can I fix this error - “/usr/bin/ld: cannot find -lX11”¶

In the configure, there is an x_libraries variable there that is set to “/usr/X11R6/lib” (around line 16371). Because it is a 64 bit system, this variable needs to be /usr/X11R6/lib64. After changing that, it should continue compiling.
