+Problems with building ginsh
+----------------------------
+
+The most common reason why this doesn't succeed is the absence of
+libreadline and/or the corresponding header files.  Depending on what
+your system/distribution is, you will have to install a package called
+libreadline and maybe libreadline-dev.  If your system's vendor
+doesn't supply such packages, go to <ftp://ftp.gnu.org/gnu/readline/>
+and compile it yourself.

-You need to specify
-  --with-cint=$CINTSYSDIR
-...
+Please see <http://root.cern.ch/root/Cint.html> to learn about Cint
+and install it prior to installing ginaccint.  For the interpreter-
+compiler `makecint' to work properly, the Makefiles need to know where
+Cint has its system directory.  This is usually done by exporting
+$CINTSYSDIR to point to the proper place.  With GiNaC you may either
+try to export that variable and type
+ $ ./configure --with-cint
+or specify it directly on the command line by saying
+ $ ./configure --with-cint=/my/path/to/cintsysdir
+This variable does not have to be exported for running the installed
+binary: since the actual program is started by a launcher that sets it.
+Enjoy!
