I have installed it on two servers per the howto. It is tedious to download and install all the perl module rpm's, (but it's alot easier now that the howto has links! Great improvement!) and you also have to fiddle with the metadot.conf file - not only the mysql stuff, but the skin_template_dir line needs to look like:
skin_template_dir = /home/e-smith/files/ibays/Primary/html/metadot/sitedata/skin
This will take care of the error you will get on the top of each page.
I would like to see a howto putting metadot in an ibay and/or placing it as the primary ibay, not /metadot, and an rpm packaging up all the perl stuff.
Not that I am ungrateful - My sincerest thanks goes to the author of the existing howto.
