I just made all these steps again, to see, if it's really working for me, and I now recall
why I get this error with Ginsh: The configure script didn't find the headers for
libreadline. They are on my system, but when I set their path to the compiler flags, I got
some strange compilation error I didn't understand so far, so I preferred a working Ginac
without Ginsh.
