Most probably a package specific setup routine that makes a connection
to the X server -- for whatever reason. The environment is probably
modified at that point (e.g. by portages sandbox), so it doesn't work
with a forwarded X connection.

Maybe you can temporarily overcome that by using e.g. Xnest (since you
already have X forwarding running) or Xvnc.
