1. Wget ftp://ftp.gnu.org/pub/gnu/gettext/gettext...t-0.12.1.tar.gz
2. Untar file as tar -zxvf gettext-0.12.1.tar.gz
3. cd to the directory containing the package's source code and type ./configure to configure the package for your system. If you're using csh on an old version of System V, you might need to type sh ./configure instead to prevent csh from trying to execute configure itself.

Running configure takes awhile. While running, it prints some messages telling which features it is checking for.

4. Type make to compile the package.
5. Optionally, type make check to run any self-tests that come with the package.
6. Type make install to install the programs and any data files and documentation.
