Are you packing the CVS version of octave-forge or release 2006.03.17 ?

On my end, octcdf from release 2006.03.17 compiled from source actually 
do work with octave-2.9.4-8.fc5 and octave-2.9.5-2.fc5. In case you are 
using the CVS version, you would need the CVS version of today (2nd May) 
for octcdf.

Concerning the hyphen in ov-netcdf.oct, I can make the change if it is 
really necessary, but it  never posed a problem to me. Instead of "which 
ov-netcdf" you can type "which netcdf":
octave:1> which netcdf
netcdf is the dynamically-linked function from the file
/home/abarth/Octave/octcdf/netcdf.oct

Did you tried to run example_netcdf.m or nctest.m ?

In order to verify if ov-netcdf.oct contains undefined symbol, you can 
check the linked libraries with:
$ ldd ov-netcdf.oct
        libnc-dap.so.3 => /usr/lib64/libnc-dap.so.3 (0x00002aaaaabfc000)
[...]
The ov-netcdf.oct file in octave-forge seems not to be linked against 
nc-dap (or netcdf).

Thanks and regards,
Alex
