Install AOLserver 4.5
If you want to install AOLserver 4.5 you could follow the instructions for AOLserver en:aolserver-install and replace 40r10 with 4.5 (more or less ...).
Alternatively follow the instructions or download it as a shell script (recommended) or download a full archive aolserver45-oacs.tar.bz2.
If on "OS X" the install fails for nspostgres with undefined symbols, execute the following command:
gcc -pipe -dynamiclib -install_name /usr/local/aolserver45/lib/libnspostgres.dylib -o libnspostgres.dylib nspostgres.o -L/usr/local/aolserver45/lib -lnsd -lnsthread -L/usr/local/aolserver45/lib -ltcl8.4 -lpthread -framework CoreFoundation -lnsdb -L/usr/local/pgsql/lib -lpq
