To build tla-1.2 as a debian-woody package, simply extract debian.tar.bz2 to
the top-level of your extracted tla-1.2 source-tree and type:
./debian/rules build
fakeroot ./debian/rules/binary

This builds tla and newer diff && diff3 which are put into the package in
a nonstandard location (/usr/share/tla)
(and tla uses them instead of the normal system ones)

You can also find a prebuilt package for i386 here (Which also includes the
diffutils).

If you want to use tla on Solaris, you can use my Solaris PKGs available at:
