KBiff is typically available in most of the major (and not so major) Linux distributions. Try using yum, apt, zypper, emerge, or whatever your distribution's install tool of choice is, to search for kbiff. Odds are, a relatively recent version is there.
- Download v4.0 sources. [SRPM] [LSM] [changes]
- Download binary release: openSUSE 11.3 RPM [i586] [x86_64], openSUSE 11.4 RPM [i586] [x86_64],
You can get the latest development code from KBiff's Mercurial repository. KBiff is a very mature product now so there really isn't a development branch, per se. Any patches in the repository that aren't in a release are tested changes that are just waiting for the next release.
$ cd kbiff
$ mkdir build; cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr ..
$ make; make install
$ hg pull
$ hg update
