Can't compile ginsh

I have compiled GiNaC on a Debian Linux Potato box. The library compiled OK and I have successfully tested a few examples from the tutorial with correct result. However I can't get ginsh to compile, it fails on ginsh_parser.cc. Any tips/patches? //Gunnar Isaksson - To UNSUBSCRIBE, email to ginac-list@ginac.de with a subject of "unsubscribe".
