Thanks for the pointer. Ghostscript 8.61 Universal was also installed 
via MacPorts. Here is the output from convert -debug on Intel and PPC 
platforms:

convert: Postscript delegate failed `test.ps': No such file or directory.
convert: missing an image filename `test.png'.

On PPC Macs, gs is invoked twice, with -c showpage option the second 
time. I am not sure why it would be invoked twice on PPC but only once 
on Intel.
