Architecture / Installation

Hate to holler for help this early in the process, but I'm stumped. I'm doing a new install of 6.1 on a RHEL 4.8 box, which means MySQL 5.0 and PHP 5.1.6. I've created a database and a user, and given the user all necessary rights. And so to the install. I get to 'Set the Database Connection', choose 'Use Existing Connection', click Install, and get an

-- --------------------
-- Database : Tiki
-- --------------------
This command is not supported in the prepared statement protocol yet

when it tries to convert to utf8.

So I can't use utf8, but should be able to muddle through in Latin-1, right? I click continue, configure general settings, and I'm complete! Enter my Tiki; change my admin password, and:

System error.

The following error message was returned:

The query was:
SELECT `page_id`, `pageName`, `hits`, `description`, `lastModif`, `comment`, `version`, `version_minor`, `user`, `ip`, `flag`, `points`, `votes`, `wiki_cache`, `cache_timestamp`, `pageRank`, `creator`, `page_size`, `lang`, `lockedby`, `is_html`, `created`, `wysiwyg`, `wiki_authors_style`, `comments_enabled` FROM `tiki_pages` WHERE `pageName`=?

Values:

1. User:admin

The built query was likely:
SELECT `page_id`, `pageName`, `hits`, `description`, `lastModif`, `comment`, `version`, `version_minor`, `user`, `ip`, `flag`, `points`, `votes`, `wiki_cache`, `cache_timestamp`, `pageRank`, `creator`, `page_size`, `lang`, `lockedby`, `is_html`, `created`, `wysiwyg`, `wiki_authors_style`, `comments_enabled` FROM `tiki_pages` WHERE `pageName`='User:admin'

and I can't go any further.

Don't _think_ the database is corrupt.

but I should have lots of php memory left - I allocated 64Mb.

I'm not sure how to troubleshoot from here - pointers in the right direction really appreciated.

Thanks...
