install weirdness with development Drupal 5.0 rc1 site

I don't know if it is fair to call this a bug, but the errors I encountered may reveal places the install could be improved.

Whereas no problems whatsoever on a fresh install, on a Drupal 5.0 rc1 site, where earlier on I had been trying to update the project modules to 5.0 myself based on the 4.7 code, I had disabled the project and project_issues modules and removed them from the module directory, but tables still existed in the database.

the following tables already exist:
project_comments
project_issues
project_issue_projects
project_issue_state
project_projects
project_subscriptions

So, I had the following experience:

Install of modules
Untarred modules (into ./sites/all/modules)
Administer modules shows a nice Project group:

Project5.x-0.x-dev
Provides a project node type and browsing of projects.
Required by: Project issue tracking (disabled), Project releases (disabled)

Project issue tracking5.x-0.x-dev
Provides issue tracking for the project.module.
Depends on: Project (disabled)

Project releases5.x-0.x-dev
Provides a release node type to represent releases of projects.
Depends on: Project (disabled)

Install of modules
* Untarred modules (into ./sites/all/modules)

* Administer modules shows a nice Project group

Enabling project creates the following warnings:
user warning: Table 'project_projects' already exists query: project_install CREATE TABLE project_projects ( nid int(10) unsigned NOT NULL default '0', uri varchar(50) NOT NULL default '', homepage varchar(255) NOT NULL default '', changelog varchar(255) NOT NULL default '', cvs varchar(255) NOT NULL default '', demo varchar(255) NOT NULL default '', release_directory varchar(255) NOT NULL default '', version int(10) unsigned NOT NULL default '0', mail varchar(255) NOT NULL default '', documentation varchar(255) not null default '', screenshots varchar(255) not null default '', license varchar(255) not null default '', PRIMARY KEY (`nid`), KEY project_projects_uri (uri(8)) ) TYPE=MyISAM /*!40100 DEFAULT CHARACTER SET utf8 */; in /var/www/intrasteinhardtsa/includes/database.mysql.inc on line 167.

I run update.php,but no update version offered for project module (1,2,3,4,no updates available).

An examination of the database tables shows that the project_projects table is correct anyway (but what if there had been changes?).

Invoked the devel module's “Reinstall module” on project (it calls hook_install or hook_update)

Upon hitting administer to enable the project issues, was advised of the following warning:
Database schemaOut of dateSome modules have database schema updates to install. You should run the database update script immediately.

Now there is an update available for project (1)!

I hit the update button; get warnings:

user warning: Table 'intranetssa.project_releases' doesn't exist query: update_sql ALTER TABLE project_releases DEFAULT CHARACTER SET utf8 in /var/www/intrasteinhardtsa/includes/database.mysql.inc on line 167.

I can still create a Project

I go ahead cheerfully to Administer > Modules and enable the module Project issue tracking.

No warnings.

Go to update.php, no updates available.

Do devel Reinstall modules, click on Reinstall project_issue project. Nice green confirmation of reinstallation.

Hit administer; told to run update; project_issue module update “1” now available.
Following message:
