Forum OpenACS Development: More detailed problem report required
"It doesn't install" is not really a problem report that is useful to the community. You will need to provide more information that this.
If you need advice on effective bug reporting, Rafael can probably provide some suggestions for you.
Meanwhile, I just grabbed the latest OpenACS 4 CVS and it installs fine here (Red Hat 7.1, PG 7.1.3) in the early hours of 02 September 2001. So, if there was a real problem in the kernel that prevented installation, it has probably already been corrected.
Are you still unable to install from a current CVS tree? If so, please provide more detailed information on the issue, so that it can be diagnosed and solved.
