[Newbie] pier on Linux vs. OSX problem

Hi, I am new to SmallTalk(Squeak) and Seaside/Pier. I am burning the midnight oil and it's like drinking from a fire hose. But I am having fun. :) I have Squeak/Seaside/Magritte/Pier installed on 2 Debian Sarge Linux box (home and work) and also on MacBookPro. I did the following on all 3 machines. I had installed Seaside per the tutorial but I used the new seaside installer again to pull in scriptaculous etc. I wasn't sure if this was kosher but I assumed that the installer might be smart enough to figure out already installed components. But the Magritte also asked if it was ok install a newer Seaside2? On Linux every thing worked just fine but on OSX, Pier (1.0.5-alpha) did not ask about config options such as base url being /seaside/pier etc. So Pier does not work and does not appear in seaside/config either. Can some one explain if I am doing something wrong, or point me in the right direction to configure Pier. Thank you very much. bakki
