OPML again

Hi all,
WP will not correctly import my OPML file which was exported from Liferea. It will import the site title, but it will not create a link to the rss/web site. I notice that by default Liferea’s OPML doesn’t seem to add the HTML URL, just the RSS feed; I modified an OPML file and added the HTML URL, but that didn’t work.
I tried changing the echo to print in link-parse-opml.php as suggested in one post, and I also downloaded the latest nightly and copied the file over the old one as a later poster suggested.
Does the import blogroll function only work with OPML files exported from certain sites/services?
Thanks!
