This looks like the result of a typo, defining FLIBS='-IU77' instead
of FLIBS='-lU77'.  (In case your font doesn't show it the character
before 'U' is a lower case el, not an upper case eye.)

Also, Ed Hartnett came up with a much simpler solution which works
without even patching the src/fortran/cfortran.h file that comes with
the source.  I recommend using Ed's solution if it works for you:

  .. it compiles and passes all tests on mort, with absoft, with only
  the following environment vars (with compiler in my path):

    CPPFLAGS=-DAbsoftProFortran
    FLIBS=-lU77

  I didn't apply any patches, and all tests passed, so perhaps the other
  environment vars you're using are causing a problem?

That uses version 3.6.1-beta2 from:
