Done. Do you want to install the two files $buildfile $datfile
to a directory of your choice?

If you do NOT install, you have to call fortune with the path to the folder
containing the compiled cookies, e.g. 
\"fortune $PWD/build\" or 
\"fortune $PWD/build/cbbl\".

If you DO install, you should install it to a path where the fortune program can
find it.

On debian systems, this is $installpath, on other systems it might be
/usr/share/fortune or something else.

So, do you want to install (y/n)?"
