configure: WARNING: A BLAS library was detected but found incompatible
with your Fortran 77 compiler. The reference BLAS implementation will
be used. To improve performance, consider using a different Fortran
compiler or a switch like -ff2c to make your Fortran compiler use a
calling convention compatible with the way your BLAS library was
compiled, or use a different BLAS library.
configure: WARNING: qrupdate not found. The QR & Cholesky updating
functions will be slow.
configure: WARNING: arpack not found. This will result in a lack of

configure:
NOTE: libraries may be skipped if a library is not found OR
if the library on your system is missing required features.
Does anyone have some insight as to what is wrong?
