I got the stuff and it built OK.

I was unable to duplicate your problem on my Alpha.  Here's what I got:

    $ uname -a
    OSF1 ernie.unidata.ucar.edu V4.0 564 alpha
    ./sample
    NetCDF small piece of testcode
    Opening ncfile...
     Defining data_set...
       Attribut put: a = 1 and b[0]=2
     Done
     Putting values...
    Closing netcdf file
    $ ncdump sample.net
    netcdf sample {
    dimensions:
            DimA = 1 ;
            DimB = 5 ;
            DimC = 3 ;
            DimD = 2 ;
            DimE = 29 ;
    variables:
            int Var_a_scalar ;
            int Var_b_vector(DimB) ;
            int Var_c_matrix(DimC, DimD) ;
            char TEXT(DimE) ;

    // global attributes:
                    :TEST_PIECE = "Small(?) testcode" ;
                    :created_on = "DEC ALPHA OSF1 4.0b" ;
                    :value1 = 1 ;
                    :value2 = 2 ;
                    :value3 = 2, 3, 4, 5, 6 ;
                    :value4 = 2, 3, 4, 5, 6 ;
    data:

     Var_a_scalar = 1 ;

     Var_b_vector = 2, 3, 4, 5, 6 ;

     Var_c_matrix =
      0, 1,
      3, 4,
      6, 7 ;

     TEXT = "This is just a dummy string!" ;
    }

I used your makefile with its option settings modified to reflect the
location of our netCDF installation.

It appears that your Alpha differs from mine.  What kind do you have and
are you running it in an unusual mode?
