What do you think?

./configure
make
make install

Notes:

1. If you want Aspell support (for spell-cheking), you should install libaspellXX-devel package (where XX is the number of version) before you run ./configure. And what about the version? The modern one - that is the answer.

2. If you are not the Debian-package maintainer, do not use "--enable-debian" option for the configure-script. So if you have Debian, and want to build TEA from the source, run the ./configure without parameters.
