[XeTeX] "Finding" Lucida Bright fonts in XeTeX

[nachman]

I have the Lucida Bright fonts from the old "Texture" days.  Using info 
from Gary Gray I converted them to .pfb files, renamed and stored them 
in the appropriate files such as 
~/Library/texmf/fonts/type1/yandy/lumath, etc. TeXShop with the pdf  
typesetter or the ps typesetter has no trouble finding these fonts with 
the following preamble:

\documentclass[reqno]{article}
\usepackage[LY1]{fontenc}
\usepackage[LY1]{lucidabr}
\usepackage{bm}
\usepackage{amssymb}
\usepackage{amsmath,amsthm}
\usepackage{latexsym}
\usepackage{pdfsync}
\usepackage{color}
\usepackage{amsthm}

However, on the same file, with this preamble

\documentclass[reqno]{article}
\usepackage[LY1]{fontenc} % specify text font encoding
\usepackage[LY1]{lucidabr} % switch text and math fonts
\usepackage{bm}           % switch text and math fonts
\usepackage{amssymb}
\usepackage{amsmath,amsthm}
\usepackage{latexsym}
\usepackage{color}
\usepackage{amsthm}
\usepackage{utf8accents}
\usepackage{fontspec}

XeTeX generates the following error messages:

*** font hlcrima (LucidaNewMath-AltItalic: file 'lbmo') not found
*** font hlcry (LucidaNewMath-Symbol: file 'lbms') not found
*** font hlcrv (LucidaNewMath-Extension: file 'lbme') not found  )

Any thoughts?
