How to Install mathdesign on TeXlive -- mktexpk and updmap errors

Question

I'm trying to install the mathdesign package on TeXlive, and running into a slew of issues involving maketexpk and updmap failures. Are there any step-by-step instructions to accomplish this?

Here's what I've done so far:

First, I was trying to use \usepackage[garamond]{mathdesign}, but ran into this problem during a xelatex compile with LaTeX headers:

\documentclass{book}

\usepackage{amssymb,amsmath,amsfonts,fleqn}
\usepackage{theorem}% Bold Math package

\usepackage{xltxtra}
\usepackage{xunicode}
\usepackage{graphicx}
\usepackage{fontspec}
\usepackage[garamond]{mathdesign}

\usepackage[EU1]{fontenc}
\usepackage{bm}% Bold Math package -- install AFTER \usepackage[urw-garamond]{mathdesign}

% bold math and math italic macros

\def\alphab{{\protect\bm{\alpha}}}
\def\Gammab{{\protect\bm{\Gamma}}}
\def\Ab{{\protect\mathbf{A}}}
\def\zerob{{\protect\bm{0}}}
\def\oneb{{\protect\bm{1}}}
\def\Rbmit{{\protect\bm{R}}}
\def\Xbmit{{\protect\bm{X}}}
\def\Ybmit{{\protect\bm{Y}}}
\def\Zbmit{{\protect\bm{Z}}}
\def\Rbbb{{\mathbb{R}}}

\DeclareMathOperator{\tr}{tr}

A pretty fact for a square matrix~$\Ab$

So I tried to install mathdesign (which has md-gmr8y) into texmf-local by doing the following.

cd ~/Downloads/mathdesign
sudo mkdir /opt/local/share/texmf-local/tex/latex/mathdesign
sudo rsync -va ./latex/ /opt/local/share/texmf-local/tex/latex/mathdesign

sudo rsync -va ./afm/ /opt/local/share/texmf-local/fonts/afm

sudo rsync -va ./opentype/ /opt/local/share/texmf-local/fonts/opentype
sudo rsync -va ./tfm/ /opt/local/share/texmf-local/fonts/tfm
sudo rsync -va ./type1/ /opt/local/share/texmf-local/fonts/type1
sudo rsync -va ./vf/ /opt/local/share/texmf-local/fonts/vf

sudo mkdir -p /opt/local/share/texmf-local/fonts/map/pdftex/mathdesign
sudo rsync -va ./map/ /opt/local/share/texmf-local/fonts/map/pdftex/mathdesign

sudo mkdir -p /opt/local/share/texmf-local/fonts/enc/mathdesign
sudo rsync -va ./enc/ /opt/local/share/texmf-local/fonts/enc/mathdesign

sudo mkdir -p /opt/local/share/texmf-local/dvipdfm/config
sudo rsync -va ./config/ /opt/local/share/texmf-local/dvipdfm/config

sudo vi /opt/local/var/db/texmf/web2c/updmap.cfg

# mathdesign
Map mdput.map
Map mdugm.map
Map mdbch.map
Map mdpus.map
Map mdpga.map
Map mdici.map

sudo mktexlsr
sudo updmap

But this results in the updmap error:

updmap is using the following updmap.cfg files (in precedence order):
  /var/root/.texlive2012/texmf-config/web2c/updmap.cfg
  /opt/local/var/db/texmf/web2c/updmap.cfg
dvips output dir: "/var/root/.texlive2012/texmf-var/fonts/map/dvips/updmap"
pdftex output dir: "/var/root/.texlive2012/texmf-var/fonts/map/pdftex/updmap"
dvipdfmx output dir: "/var/root/.texlive2012/texmf-var/fonts/map/dvipdfmx/updmap"
pxdvi output dir: "/var/root/.texlive2012/texmf-var/fonts/map/pxdvi/updmap"

ERROR:  The following map file(s) couldn't be found:
    mdpga.map (in /opt/local/var/db/texmf/web2c/updmap.cfg)

    Did you run mktexlsr?

    You can disable non-existent map entries using the option
      --syncwithtrees.

I know I put the file mdpga.map in /opt/local/share/texmf-local/fonts/map/pdftex because I can see it there and the results of mktexlsr. Is that where it should go? I'm at a loss for the limited mathdesign installation and updmap documentation.
