The old style source install is generally in at least 3 steps:
- ./configure --with-someargs
After you've "untarred" the source tree, look for the README file. Read it. It'll probably tell you to cd to the directory with the configure script, and run the script with arguments depending on what type of support and filesystem layout you need.
- make
This runs the compiler on the source code.
- make install
This installs the program(s).
Check for docs like README or INSTALL in the untarred source dir. If you can't find what you need there, take a look at the MySQL site. There should be documentation there.
