>Description:
Building of emacs-related port will fail on byte-compiling .el files,
if PREFIX is specified .

>How-To-Repeat:
1. Build dependent ports normally.
	# cd /usr/ports/x11-toolkits/Xaw3d
	# make install clean
	# cd /usr/ports/graphics/jpeg
	# make install clean
	# cd /usr/ports/graphics/tiff
	# make install clean
	# cd /usr/ports/graphics/libungif
	# make install clean
	# cd /usr/ports/graphics/png

2. Build emacs related ports with PREFIX
	# cd /usr/ports/editors/emacs21
	# make PREFIX=/usr/local/emacs21 install clean
	# cd /usr/ports/editors/tamago
	# make PREFIX=/usr/local/emacs21 install

3. Watch tamago port fail to build due to not finding
   /usr/local/bin/emacs-21.3.
