fontconfig cvs build fails on Red Hat 9

[Murray Cumming Comneon com]

I've had this problem for a few weeks now, in jhbuild's GNOME 2.6 moduleset.
Is there some rpm that I'm missing? I have the strange feeling that I've
asked this before but forgotten the answer, but I can't find anything by
googling.

Note that --disable-docs only disables the doc folder, not this.
