(Not sure if you guys are using Google Code's Issue Tracker; if so, I originally filed this here: https://code.google.com/p/git-core/issues/detail?id=18 ) What steps will reproduce the problem? 1. Build git from source. 2. Download git-manpages-*. 3. Install both. 4. Attempt to build and install contrib/subtree. What is the expected output? What do you see instead? Expected: git-subtree goes into $PREFIX/libexec/, and git-subtree.1 goes into $PREFIX/share/man/man1/. Actual: git-subtree.1 fails to be generated because my system doesn't ship asciidoc and xmlto. What version of the product are you using? On what operating system? v1.7.12.2 and v1.8.0.rc0.18.gf84667d, on OS X 10.8.2. Please provide any additional information below. Prototype patch attached.
