>Description:
	Due to insufficient checking of object (library/executable) paths, when having some ports installed in default LOCALBASE/X11BASE, installing ports with changed *BASE will often fail, because dependencies will be found among ports installed in default dirs, but won't be used, which will lead to compile errors.
	
>How-To-Repeat:
	# cd /usr/ports/devel/sdl12 && make install

	SDL installs normally

	Now,

	# mkdir /usr/X11R6_test /usr/local_test /var/db/pkg_test
	# X11BASE=/usr/X11R6_test LOCALBASE=/usr/local_test PKG_DBDIR=/var/db/pkg_test make install

	Note, that for current X11BASE, LOCALBASE and PKG_DBDIR values, nothing at all is installed.
	However, required libs will be found:

	===>  Extracting for sdl-1.2.9,2
	=> Checksum OK for SDL-1.2.9.tar.gz.
	===>  Patching for sdl-1.2.9,2
	===>  Applying FreeBSD patches for sdl-1.2.9,2
	===>   sdl-1.2.9,2 depends on executable: nasm - found
	===>   sdl-1.2.9,2 depends on file: /usr/local_test/bin/libtool15 - not found

	(libtool gets installed)

	===>   sdl-1.2.9,2 depends on shared library: aa.1 - found
	===>   sdl-1.2.9,2 depends on shared library: vga.1 - found
	===>   sdl-1.2.9,2 depends on shared library: X11.6 - found
	===>  Configuring for sdl-1.2.9,2

	And, of course, file-not-found errors wil occur:

	SDL_x11video.h:31:22: X11/Xlib.h: No such file or directory
	SDL_x11video.h:32:23: X11/Xutil.h: No such file or directory
	SDL_x11video.h:33:23: X11/Xatom.h: No such file or directory

	etc.
