Forum OpenACS Q&A: Re: dotlrn installation. Invalid file type "message_catalog"

You may need 4.6.1, which you can get from CVS by checking out the branch tagged "oacs-4-6".  We'll have a 4.6.1 beta2 tarball available in the next few days, it's just awaiting some testing on a server at Sloan, and there's been a bit of a hassle getting data imported onto that server (typical Unix/Oracle "gotcha" stuff)
