Your log rename is failing because ':' is not a legal filename character. In your AOLserver config file, change to something like:
ns_section "ns/server/$server/module/nslog"
ns_param rollfmt %Y-%m-%d-%H_%M
The last real OpenACS install I did was before the mktree code was added. Do those files exist in your /packages/acs-templating/www/resources/ directory?
Do you have gunzip installed? Where? It is available as part of Cygwin. If you're having trouble installing from a .apm file, you can try checking out the package you need from CVS.
