Looking into this further, it is a problem with the config file. It can't find tcl headers (at least on my gentoo box) which is true if you are running 3.5 aolserver.
If you are using AOLserver >= 3.5 you also need to specify your tcl config: --with-tcl=/usr/lib or wherever.
Now everything is fine. I will add a little upgrade howto and I think that the default param in .info should be changed to 0.3.1 instead of 0.2
