I found that now this version doesnot work too. So I delete Numeric
21.0 complettely then install Numeric 22.0 again. After that the error
message changed to:

$ python
Python 2.2.2 (#1, Dec 22 2002, 17:44:21) 
[GCC 3.2.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import LinearAlgebra
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.2/site-packages/Numeric/LinearAlgebra.py", line 10, in ?
    import MLab
  File "/usr/lib/python2.2/site-packages/Numeric/MLab.py", line 20, in ?
    import RandomArray

    seed()
  File "/usr/lib/python2.2/site-packages/Numeric/RandomArray.py", line 26, in seed
    x = int(t/base)
OverflowError: float too large to conver

I can not figure out what is happenning. Temporarily, I import
LinearAlgebra this way:

try:
	import LinearAlgebra
except:
	import LinearAlgebra

And this worked, for Numeric 22.0 on python 2.2.2
as well as for Numeric 21.0 on python 2.2.2 .
