I updated the install document yesterday.

I don't object to support for ISL 0.12.2, but someone has to implement
an appropriate header file incantation for the Graphite source files
WITHOUT reordering it again nor including ISL header files first --
before system.h.  Some GCC header files must be included first in GCC
source files.
