AOLServer 4.5.0 and a set of modules are available in the FreeBSD ports tree (and as binary packages for i386 and amd64 architectures).
More information on AOLServer ports:
http://www.freebsd.org/cgi/ports.cgi?query=aolserver&stype=all
There are OpenACS and dotLRN ports available, too. There will be more dependencies added to these ports in the future.
More information on OpenACS ports:
http://www.freebsd.org/cgi/ports.cgi?query=openacs&stype=all
Location of OpenACS ports:
www/openacs (vesion 5.3.0)
www/openacs-dotlrn (version 2.2.1)
The OpenACS ports have the following dependencies (these are installed automatically with the OpenACS ports):
lang/tcl84-thread
www/tdom
www/aolserver
www/aolserver-nscache
security/aolserver-nsopenssl
databases/aolserver-nspostgres
security/aolserver-nssha1
There is ongoing work on the ports.
These dependencies will be added in the near future but can be installed at this time manually:
www/aolserver-xotcl
www/tclwebtest
devel/tcllib
I will publish new installation instructions in the OpenACS online documentation soon.
