Subject: [PATCH] academic/sage: Downgraded to 7.2.

Built in python was compiled against UCS-4.
Slackware's readline is not linked to ncurses, causing
problems similar to here: https://bugs.archlinux.org/task/39731.

We will try to bump sage in the next Slackware release
when everything is fixed, including Python that is
compiled against UCS-4.

Adding a note for now.

Thanks to Mehran Hosseini for the bug report.

+Future SAGE (7.3+) requires some changes in Slackware's core packages:
+- readline must be linked to ncurses
+  Get readline's SlackBuild script, change this line
+  make $NUMJOBS static shared || make static shared  || exit 1
+  into
+  make $NUMJOBS static shared SHLIB_LIBS=-lncurses || make static
+  shared SHLIB_LIBS=-lncurses || exit 1
