The last line above indicates a severe problem with your C compilation
environment.  The reason can be found in your "config.log" file:

> configure:1085: checking C compiler "/usr/bin/gcc"
> configure:1094: /usr/bin/gcc -c -O3 -funroll-loops -march=k8 -m64 
> -mfpmath=sse -msse2 -ffast-math -mcmodel=medium -DNDEBUG -Df2cFortran
>  -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE conftest.c 1>&5
> cc1: bad value (k8) for -march= switch
> cc1: bad value (k8) for -mcpu= switch

Apparently, the "-march=k8" option is illegal.  Given that you specified
the CFLAGS environment variable as

> CFLAGS='-O3 -funroll-loops -m64 -mfpmath=sse -msse2 -ffast-math 
> -mcmodel=medium' ; export CFLAGS

It seems likely that the CFLAGS variables was not correctly made an
environment variable.

A similar problem exists with your Fortran compiler:

> checking user-defined Fortran-77 compiler "/usr/bin/g77"... failed to compile 
> test program

For which the problem is also explained in your "config.log" file:

> configure:1383: checking user-defined Fortran-77 compiler "/usr/bin/g77"
> configure:1389: /usr/bin/g77 -c -O3 -funroll-loops -march=k8 -m64 
> -mfpmath=sse -msse2 -ffast-math -mcmodel=medium -Wno-globals conftest.f
> ./configure: line 1: /usr/bin/g77: No such file or directory

Given that you specified the Fortran-77 compiler as

> FC=/usr/pgi/linux86-64/5.1/bin/pgf77 ; export FC

it seems likely that the FC variable was not correctly made an
environment variable.

Please do a "make distclean" and retry the build with the environment
variables settings that you used before. before (re)executing the
"configure" script, verify the settings with the following commands:

    env | grep CFLAGS
    env | grep FC
