Finding a relative prime


I'm using Mathematica 3.0 for the Mac, and I'm trying to figure out how
to get it to pick a random number that is relatively prime to another
number, p-1, where p is prime.  In other words, pick a random number k
such that 1) k is between 2 and p-1, and 2) k is relatively prime to p-1.
How can I do that in Mathematica 3.0?
