It never dawned on me that people might want to install Alpha 2 and continue to use it. Personally, I can't fathom not using a nightly. I'm big on stability, but considering that Haiku is very much in an alpha state, I expect problems. Some revisions are better than others. Right now, one of my machines is running r38082, which is a nice, reasonably stable build, but it apparently has some symbols that Alpha 2 lacks. Looks like I'll be putting out an Alpha2 build tomorrow. ;-)
Using development builds of Paladin are not normally what you might expect of a development build for other projects. I don't use release builds of Paladin -- I use the bleeding edge. If something breaks, I un-break it because otherwise I can do any further Paladin development. Using a development build of Paladin also tends to have newer features and fixes than can be found in the releases.
If you want to continue to run Alpha 2, that's fine. I'll be posting an Alpha 2 build soon. Here's how to build Paladin from source. You'll need Mercurial installed to do so.
From the Terminal run these commands:
hg clone http://paladin.hg.sourceforge.net:8000/hgroot/paladin/paladin
This will actually build Paladin, PalEdit, and parts of the as-yet-unreleased packaging system and create a package on your Desktop. Open it and it will install Paladin on your system. If you want to use ccache or fastdep, copy them from the Paladin install folder to /boot/common/bin. The bug causing them to be installed in the wrong place is the reason why the packaging system isn't officially released yet.
