Installation should be simple, as there is nothing to compile.
You have what is one of three packages.

1) A source package
2) Slackware Package


FONTpage was written and tested using 
pyGTK-2.8.6, python-2.4.3 and GTK-2.8.17

The source code needs all of the above to run.
The binary (Slackware/Ubuntu) distributions do not need pygtk.

 (Check the homepage for latest releases. The 
  binaries are not as up-to-date as the source.)
