You will have a better chance of getting answer if you submit support questions to address@hidden. From looking at your config.log it appears that you are trying to use the GNU C compiler with the intel fortran compiler. If so, you need to make sure that you provide the -m32 option to the C compiler (CFLAGS=-m32) or else GNU will build 64-bit code. (Intel is a 32-bit compiler by defauly, GNU 64 by default). Alternatively you could also use the intel C compiler (CC=icc). Good luck! Ed -- Ed Hartnett -- address@hidden
