I have built a new binary for p7zip and posted it on haikuports download page: p7zip-4.61-gcc2-2008-12-03.zip The diff attached to http://dev.haiku-os.org/ticket/2014 should still work for adding p7zip to expander. Can we add this to Haiku's Optional Packages on haiku-files? I see that there's already a .7z Haiku package icon in place, looks nice. Note that this now passes all of the tests, including the SMP tests that failed on 4.57 a few months ago. -scottmc
