if you have problems with compiling, i would rather go and try to
minimized the sources of errors. i.e. use a precompiled version of
the compiler, do not use libint and use a precompiled BLAS/LAPACK
if possible (MKL for example works just fine with g95).

you didn't set G95_INC and thus -ffree-form will be interpreted
as argument to the "-I" flag. this is the reason for the error
message indicating that g95 tries to interpret the code f77 style
fixed format.  => PEBCAC
