Here's what I did: First, get the latest version of Xcode that's compatible with your OS. You can find older versions of Xcode by clicking on "Developer Tools" on the right side of this page: http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wa/downloads http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/w... (you may need a free Apple developer account). sceaga has a branch for Tiger and another branch for PPC, I happened to be using Tiger on PPC, so I picked the Tiger branch. From https://github.com/sceaga/homebrew https://github.com/sceaga/homebrew , you want to click "Switch Branches" on the left, choose your branch, then click "Download on the right. Or, just click one of these: https://github.com/sceaga/homebrew/tarball/powerpc https://github.com/sceaga/homebrew/tarball/powerpc https://github.com/sceaga/homebrew/tarball/tiger https://github.com/sceaga/homebrew/tarball/tiger I opted to install into my home directory, rather than /usr/local, so to get it into place, all I had to do was extract the tarball, put the resulting directory where I wanted it (I called it "brew"), and then add $HOME/brew/bin and $HOME/brew/sbin to my $PATH. If you want it in /usr/local, see the instructions at https://github.com/mxcl/homebrew/wiki/Installation https://github.com/mxcl/homebrew/wiki/Installation , but in the "curl" line, replace their URL with the one you picked above. You should now be able to type "brew" and see its usage message. At this point, "brew install" worked for me, except that it wasn't chmodding binaries as executable. At the end of installations, it was giving a bunch of messages like "file: invalid option -- h". This appears to be because my 10.4 PPC version of "file" doesn't support "-h". To fix this, I installed the gnu version instead: brew install libmagic chmod +x ~/brew/Cellar/libmagic/5.04/bin/file brew link libmagic #libmagic doesn't add gnu "file" to your PATH without this command, because it doesn't want to override the OS-provided "file" After that, homebrew seems to work, with the following caveats: 1. "brew update" (which updates the package manager itself) will try to update from the non-PPC, upstream version of homebrew. I just don't use this command. 2. "brew doctor" complains that my gcc is too old (because I can't use the latest Xcode) and can't seem to detect that I have X11 installed, even though I do. I've also found the people in #machomebrew on irc.freenode.net to be a helpful bunch, although not many have experience with homebrew on PPC. Let me know how it goes!
