It seems gcc could not find cloog or ppl during configure. So graphite is
disabled right now (and therefore the test cases fail).

Your ./configure output should start like this:

ï---------------------------------------------------------------------------

The last two rows are important.

May be you missed to add "--with-cloog" or "--with-ppl" to
your ./configure.
Can you send me your config.log file?
