I have already solved this problem, but there was an error when I was trying to emerge emacs that said
and so on...
and when I tried to emerge xpdf, it said it wasn't going to compile the parts that needed X.
What I had to do is:
ln -s openmotif<tab>/Xm
then they gave me errors about -lXm not working with gcc, so to solve that:
ln -s openmotif<tab>/libXm*
then everything compiled. Hope that helps someone.
