Yes. First you untar them with tar -xvjf <packagename.bz2>
Then cd to the directory that makes and run as normal user
./configure
make
su -c "make install"
or you can d/l
checkinstall and use it. With checkinstall you issue
./configure
make
su -c "checkinstall" (rather than make install)
and it will create a Slack package for you. So if you want to
uninstall the program, you can use removepkg.
Edit: NB: Before installing with ./configure; make; checkinstall (or make install)
you should read the README and INSTALL files in the package directory.
