configure failed to detect no asciidoc

I just downloaded the latest git, and tried to build with:

 > make configure
 > ./configure
 > make all doc

build failed while "building" doc, asciidoc not found

I would have thought the configure would have detected that.....

I downloaded, built, and installed asciidoc, and re-built git, things are mostly good.

The documentation is still causing me trouble as my firewall doesn't like the html in Documentation/docbook.xsl, but that's probably a firewall issue. Is there documentation method, not requiring active web access?
