Lilypond, Pango, TeX, and metrics

[Joshua Goforth]

I'm on Mac OS X 10.4.4, Using the latest binary (2.7.35) I want to  
use Adobe's Garamond Premier Pro (OTF) for all of my lyrics. I know  
the several methods for choosing fonts, and they work, but the  
kerning is not right. (looks good, but not great) My understanding is  
that this is Pango's fault. Fine, but I need to use the precise  
kerning metrics of my font that all the rest of my apps use. I've  
tried converting my font with FontForge to TTF (thinking maybe it  
handles kerning with TTF differently) but lilypond fails to generate  
the PDF using the converted font. Must I use the TeX backend, and if  
so, could someone walk a non-guru through the steps? (I'm comfortable  
at the commandline, compiling, basic troubleshooting, etc.)
