mkoctfile problem

Hi everybody!

I tried to make a .oct-file from a  fortran-file, but had no success.
I get "error: `iau_SP00' undefined near line 2 column 1" when calling the
function.

* I started with the subroutine sp00.for from SOFA
(http://www.iau-sofa.rl.ac.uk/2008_0301/Downloads.html).
* I replaced all special Characters in sp00.for (\r\n to \n and such) and
renamed it to sp00.f (checked with vim)
* called from bash mkoctfile -o iau_SP00.oct sp00.f. This executed without
an error and returned the iau_SP00.oct-file
* started octave from bash
* added the path whit the .oct-file 
* tried to run it with and without parameters and always get the same error
(as above).

Thanks for any help!
Here is the sp00.for code:

      DOUBLE PRECISION FUNCTION iau_SP00 ( DATE1, DATE2 )
*+
*  - - - - - - - - -
*   i a u _ S P 0 0
*  - - - - - - - - -
*
*  The quantity s', positioning the Terrestrial Ephemeris Origin on the
*  equator of the Celestial Intermediate Pole.
*
*  This routine is part of the International Astronomical Union's
*  SOFA (Standards of Fundamental Astronomy) software collection.
*
*  Status:  canonical model.
*
*  Given:
*     DATE1,DATE2    d      TT as a 2-part Julian Date (Note 1)
*
*  Returned:
*     iau_SP00       d      the quantity s' in radians (Note 2)
*
*  Notes:
*
*  1) The TT date DATE1+DATE2 is a Julian Date, apportioned in any
*     convenient way between the two arguments.  For example,
*     JD(TT)=2450123.7 could be expressed in any of these ways,
*     among others:
*
*            DATE1          DATE2
*
*         2450123.7D0        0D0        (JD method)
*          2451545D0      -1421.3D0     (J2000 method)
*         2400000.5D0     50123.2D0     (MJD method)
*         2450123.5D0       0.2D0       (date & time method)
*
*     The JD method is the most natural and convenient to use in
*     cases where the loss of several decimal digits of resolution
*     is acceptable.  The J2000 method is best matched to the way
*     the argument is handled internally and will deliver the
*     optimum resolution.  The MJD method and the date & time methods
*     are both good compromises between resolution and convenience.
*
*  2) The quantity s' is obtained from polar motion observations by
*     numerical integration, and so is in essence unpredictable.
*     However, it is dominated by a secular drift of about
*     47 microarcseconds per century, which is the approximation
*     evaluated by the present routine.
