Thus you're not using the standard LaTeX graphicx package inside 
/usr/local/teTeX/share/texmf.tetex/tex/latex/graphics/, but the 
modified plain TeX version inside 
/usr/local/teTeX/share/texmf.tetex/tex/plain/graphics/.

What does the modification do for graphicx.tex? Let's see:

	% Plain TeX interface to graphicx package.
	% David Carlisle

	\input miniltx

	\def\Gin at driver{dvips.def}
	\input graphicx.sty

	\resetatcatcode

First it loads the file miniltx.tex emulating in plain TeX a basic set 
of LaTeX commands, then it selects the [dvips] option (= loads 
dvips.def) for the LaTeX package graphicx.sty, and finally it loads 
this package.

Same holds for color.tex:

	% Plain TeX interface to color package.
	% David Carlisle

	\input miniltx
	\makeatletter
	\def\Gin at driver{dvips.def}
	\input color.sty

	\resetatcatcode

which loads, in plain TeX, the LaTeX package color.sty with the [dvips] 
option.

Personally I wouldn't trust the modifications to be robust enough for 
allowing use of graphicx.tex and color.tex in plain TeX in all 
situations, and I would either use the graphicx and color packages 
inside LaTeX or the driver-specific syntax (i.e. specific to dvips, 
pdfTeX or XeTeX) inside plain TeX.

Normally, as explained above, you can't. I see two possible remedies 
though, assuming you've installed a recent TeX i-Package and thus your 
file /usr/local/teTeX/share/texmf/web2c/texmf.cnf contains:

% XeTeX
TEXINPUTS.xelatex =	.;$TEXMF/{xetex,tex}/{xetex,latex,generic,}//
TEXINPUTS.xetex   =	.;$TEXMF/{xetex,tex}/{xetex,plain,generic,}//

which defines which TeX directories are searched when XeTeX is used and 
in which order.

First solution: create inside ~/Library/texmf/tex/xetex/latex/graphics/ 
a file graphics.cfg containing:

\ExecuteOptions{xetex}

This should make sure that when graphicx.sty is read the file xetex.def 
is read automatically, superseding the choice of dvips.def made in 
graphicx.tex.

Second solution: create inside 
~/Library/texmf/tex/xetex/plain/graphics/ a copy of graphicx.tex, and 
replace the line:

	\def\Gin at driver{dvips.def}

by:

	\def\Gin at driver{xetex.def}

Finally another solution would be to use XeTeX's graphic insertion 
primitives instead of the graphicx package. Namely, to replace

	$$\includegraphics[width= 10cm]{Fourier5.pdf}$$

by:

	$$\hbox{\XeTeXpdffile "Fourier5.pdf" width 10cm}$$

This should work (see above). But I don't understand what you mean 
about /Library/teTeX/ and /Library/texmfl/ (why the "l"?). A directory 
Library/texmf/ should exist inside your home directory, not at the root 
level of your hard drive, namely it should be ~/Library/texmf/ not 
/Library/texmf/. The directory /Library/teTeX/ at the root level of 
your hard drive should be an alias to the invisible directory 
/usr/local/teTeX/, which contains everything installed by the TeX 
i-Package inside i-Installer. Did you install TeX without using 
i-Installer? If so, I can't be of much help.
