Build error with current source release

Hi

I hope it is okay to ask such a question here.

I cloned the current source tree and tried to build it and I get the following error. Could someone tell me why and if there is an easy way to fix it? I’m running on a Mac and everything ran fine up to this error. Is is an excerpt from my typescript file.

Can you open this link in your browser/do you need a proxy server to connect to the internet? When I navigate to that URL it loads for me; I'm wondering if this is a firewall preventing you from accessing the dtd

It has been long since I had to deal with a problem like this in my set-up but it was a host configuration error that always wanted to download these docbook DTDs by not having proper XML catalog entries (and failing to download them, which as you can see is the error you are getting).

Sorry, no, I do not do Macintoshes, so even if I remember exact steps I took to fix my host configuration error several years ago on my Debian box, I suspect that the solution would not apply to you.

If you aren't opposed to using Homebrew, then I believe installing the docbook package will help you here. I installed xmlto that way, which automatically brought in the docbook packages for me.
