Fontconfig - Feb 2009 - lcdfilter constants not recognized

I''m using Fontconfig 2.6.0 (on Gentoo Linux).  Some applications result
in this fontconfig error message at startup:

Fontconfig warning: "local.conf", line 11: invalid constant used : 
lcddefault

"local.conf" contains these entries:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!-- /etc/fonts/local.conf file to configure system font access -->
<fontconfig>
<match target="font">
   <edit name="autohint"
mode="assign"><bool>false</bool></edit>
   <edit name="antialias"
mode="assign"><bool>true</bool></edit>
   <edit name="hinting"
mode="assign"><bool>true</bool></edit>
   <edit name="hintstyle"
mode="assign"><const>hintslight</const></edit>
   <edit name="lcdfilter"
mode="assign"><const>lcddefault</const></edit>
   <edit name="rgba"
mode="assign"><const>rgb</const></edit>
</match>
</fontconfig>

I''ve tried all lcdfilter constants (lcdnone, lcdlegacy, lcdlight, 
lcddefault) but all of them are reported as invalid.

I use the live ebuild for fontconfig, but my last compile grabbed the
same version as in the 2.6.0 tar.

They work for me.  Try this:

:; grep -lF lcdnone /usr/lib/libfontconfig.{a,so}

Does that string appear in the .a and .so?  Do the other lcd constants?

I tried running pango-view with FC_DEBUG set to each power-of-two from 1
to 1024 and found references to lcdfilter in FC_DEBUG=4''s output.

My conf does:

,----[ 99-filter-by-hints.conf ]
| <?xml version="1.0"?>
| <fontconfig>
| 
|  <match target="font" >
|    <test name="hinting" compare="eq">
|      <bool>false</bool>
|    </test>
|    <edit mode="assign" name="lcdfilter" >
|      <const>lcdlight</const>
|    </edit>
|  </match>
| 
|  <match target="font" >
|    <test name="hintstyle" compare="eq">

|    <edit mode="assign" name="lcdfilter" >
|      <const>lcddefault</const>
|    </edit>
|  </match>
| 
| </fontconfig>
`----

And those settings do get used, according to the FC_DEBUG output.

I don''t see anything in the 2.6.0-r2 ebuild which would be different.
