[ncl-install] Cannot find -liconv

[Mary Haley]

It looks to me like you have an older gfortran that doesn't recognize
"-fPIC".

What does:

  gfortran --version

report?

You can try removing "-fPIC" from the compile line to see what happens.
This is normally the default anyway, so it's not critical that you include
it.
