Hi guys,
I finally succeded in getting everything to run right. I had to go back to aolserver 4.0.8 as couln't manage to start 4.0.9b.
In the end, I used the following software for my installation on my PowerBook G4 running Mac OS X 10.3.5:
tcl 8.4.7
readline 5.0
postgres 7.4.5
aolserver 4.0.8
nscache 1.5
nssha 1
nsrewrite
nspostgres 4.0
tdom 7.8
Thanks to all of you who helped me.
Best regards,
Jose Lucero
