Trying to configure /build gcc 4.9.1 from source on CentOS6.5 (x86_64)
The ./configure looks like:
mkdir ../gcc-build && cd ../gcc-build && ../gcc-4.9.1/configure
LDFLAGS="-L/usr/local/lib, -L/usr/local/lib/cloog.isl, **-L/opt/x86_64/isl-0.12.2/lib**,

But it fails with the following:
- checking for the correct version of the gmp/mpfr/mpc libraries... yes
- checking for version 0.10 of ISL... no
- checking for version 0.11 of ISL... no
- checking for version 0.12 of ISL... no
- configure: error: Unable to find a usable ISL. See config.log for details.
Not sure how else to declare the ISL path, it is also in my LD_LIBRARY_PATH.
