Most users who realize that INSTALL files still exist should simply follow the directions at https://www.torproject.org/docs/tor-doc-unix If you got the source from git, run "./autogen.sh", which will run the various auto* programs. Then you can run ./configure, and refer to the above instructions. If it doesn't build for you: If you have problems finding libraries, try CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib" \ ./configure or ./configure --with-libevent-dir=/usr/local rather than simply ./configure.
