Which platform do you use to compile? In this case I noticed that the app doesn't use Xcode cause it's too related to the architecture and the main purpose of the author is make it cross-platform.
I noticed a little difference about the size of the 2 packages, the PPC is something like 18Mb, yours is 2Mb.....What does it depend on?
automake? Something related to Gnu Autotools... How can I do that in mac os X?
How can I install those components (Gnu ones)?
Where to give the command? In the terminal?
I'm on deadmoo's 10.4.1. Yes, core of shakespeer is cross-platform and consist from two CLI daemons - sphubd and sphashd, aqua gui is just a wrapper for them. About use of Xcode - you can always compile Xcode projects from command line too, just use /usr/bin/xcodebuild. Concerning different size - i don't know why.. need to analyze ppc package to figure out.
You're right about automake, and it's included in Xcode tools by default, but shakespeer's autogen.sh needs latest version of it to generate configure script, so i download and compile it myself.
Yep, the whole thing builds from command line.
