Attempt to install on ubuntu 12.04 on intel x86_64 fails at the configure step. On searching, I found some claims that it is because on the step, configure:5905: checking for version 0.11 of ISLit uses the value for the previous step, configure:5857: checking for version 0.10 of ISL and doesn't update the value. Though I thought that was fixed. Any suggestions? Thanks.

See config.log for details. I'm following the instructions given with the distribution. The versions used are,gmp-5.1.3/mpfr-3.1.2/mpc-1.0.1/isl-0.11.1/cloog-0.18.0/ cloog was configured using,./configure --prefix=/home/rishi/local --with-bits=gmp --with-gmp-prefix=/home/rishi/local --with-isl=system --with-isl-prefix=/home/rishi/localas described in the instructions. All of them pass their corresponding make checks.
