[gentoo-user] having problems building webkit-gtk

I have been having problems building webkit-gtk right along through the
various versions, but this one stumps me completely -- I get the error:

I have search through google and bgo and found nothing -- how can I fix
this one?

Thanks in advance for any suggestions.
