Thanks for doing this Rolf.
I tested the included directions for install on OS X 10.4.10
and it returned an error on make/make install as hightlighted here:

I then tested the directions as outlined for OpenACS 4.X in the
CONFIG file. I tried it on Ubuntu server and _I think_ it worked
after editing the CONFIG file so that it includes the
--with-tcl bit as highlighted here (I included the error as
well):
