[Zope] GDChart on Linux

[Hung Jung Lu]

OKie, I now remember I did succeed in building GDChart on Linux. :)

Let me repost here a message exchange with Mike Steed a while back in the 
Python mailing list, so in the future I won't get lost again. :)

I became aware of this problem several days ago, but being the slacker
that I am, I have not yet put an updated archive on the web.

Here's the fix.  In gd-1.8.1/Makefile, change line 18 from:

CFLAGS=-O

to:

CFLAGS=-O -DHAVE_JPEG

And change line 25 from:

LIBS=-lm -lgd -lpng -lz

to:

LIBS=-lm -lgd -lpng -lz -ljpeg

Then if you rebuild libgd and the Python interface, it should all work.
Sorry for the hassle.
