I just checked by converting the test file to Mac OS Roman encoding,  
and replacing \usepackage[utf8]{inputenc} by \usepackage[applemac] 
{inputenc}: same problem. I also tried to replace \usepackage[T1] 
{fontenc} by \usepackage[LY1]{fontenc}: no change.

Actually the problem lies, exactly as you said, in the font itself and  
in the encoding files in /usr/local/gwTeX/texmf.gwtex/fonts/enc/dvips/ 
gtamacfonts/:

- The enc files refer to the glyph ä under the name a_dieresis, and  
similarly for the other glyphs a_tilde etc. This glyph is expected at  
position 228.

- Opening the file HoeflerText.ttf created when installing the TeX i- 
Package under Tiger, and corresponding to version 5.0d7e2 of the font,  
the glyph ä is indeed at position 228, with name a_dieresis. Many  
thanks to Herb Schulz for sending off-list a copy of this file  
yesterday night.

- Opening the file /usr/local/gwTeX/texmf.gwtex/fonts/truetype/ 
gtamacfonts/hoefler/HoeflerText.ttf created when installing the TeX i- 
Package under Leopard, and corresponding to version 6.0d7e1 of the  
font, the glyph is still at position 228, but its name is now  
adieresis (without the underscore).

Thus it seems that in the version of Hoefler shipped with Leopard, all  
underscores have vanished from glyph names. Probably a short-term fix  
for gtamacfonts (untested) would be to edit manually the encoding  
files inside /usr/local/gwTeX/texmf.gwtex/fonts/enc/dvips/ 
gtamacfonts/, to suppress the underscores.
