@@ -60,6 +60,10 @@ The following packages are required to install PSPP:
     * Perl (http://www.perl.org/), version 5.005_03 or later.  Perl is
       required during build but not after installation.
 
+    * Python (https://python.org/), version 2.7.  Some tests require
+      Python; if it is missing, those tests will be skipped.  PSPP
+      does not otherwise require Python.

     * iconv, which should be installed as part of a Unix-like system.
       If you don't have a version already, you can install GNU
       libiconv (http://www.gnu.org/software/libiconv/).
