Hi Jon,

In AliceServer.mpl there is the assignation:

pi := Pi:

(line 96 or 97 depending on whether you get it from the distribution
or CVS develop_2_1).

It seems that you have added: 
  with(numtheory):
to probably Make.mpl and AliceServer.mpl (where there are the lines
  with(linalg):
  with(stats):
).

The problem is that numtheory defines a function pi ...

  > ?numtheory,pi
  numtheory[pi] - number of primes less than or equal to

  Calling Sequence
     pi(n)

  Parameters
     n - expression, assumed to be of type integer

  Description
  - The function pi(n) computes the number of prime numbers less 
    than or equal to the given integer n. 

  ...

So if you want to keep that, you should comment out or remove line
96 or 97 of AliceServer.mpl.

  Regards,
  Greg
