I tracked down the netcdf error is one of indexing with Python2.4 with 
numpy integers.  So while int64 is okay (as it should be) but most of 
the other integer types fail. I have added this to the the ticket.

 >>> import numpy as np
 >>> alist=['1','4','6']
 >>> alist[np.int64(0)]
'1'
 >>> alist[np.int32(0)]
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
TypeError: list indices must be integers
 >>> alist[np.int8(0)]
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
TypeError: list indices must be integers
 >>> alist[np.int16(0)]
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
TypeError: list indices must be integers
