I get an error trying to install the module on what appears to be Drupal 4.7.2. Here's the error message I get (actual paths substituted with fake ones):

user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'custom_header longtext,site_name custom_header_format int,tags i query: CREATE TABLE ljxp ( uid int PRIMARY KEY,active int,host varchar(255),name varchar(255),pass varchar(255),community varchar(255),site_name varchar(255),site_name custom_header longtext,site_name custom_header_format int,tags int,privacy varchar(20),comments int,post_type varchar(20),cut_text varchar(255)); in /path/to/includes/database.mysql.inc on line 120.

BTW, on a slightly unrelated note, the first time I tried to preview my comment, it majorly complained at my webpage URL. After looking at it for a moment, copying it to firefox to make sure it was valid, I guessed that it didn't like the space at the end of it. And, sure enough, eliminating the space fixed the complaint. That, however, certainly seems to be a textbook definition of "broken". Just FYI.

Oh, other information that would be extremely relevant. I'm using MySQL 5.0.24a.

Ok, I think I found the problem. This diff for ljxp.install seems to fix everything. I haven't tried out cross posting yet, though and now it's after midnight so that'll have to wait. :-)
