there you go. You solved it yourself (with a little nudge from me and
a big nudge from your error log).

If you insist on using Jpeg, recompile the program correctly (it seems
that your mapserv does claim that it supports jpeg, but I don't know
what is going on there), else use PNGs or GIFs. Should keep you busy
for a while.

Good luck.
