Hi,
my error was that the "quote" was actually a different unicode char (from the copy/paste), therefore gsi did not understand it as a quoted symbol but as an unquoted (undefined) symbol.
Ah yes! Copy pasting Scheme code from the PDF manual is not a good idea, in particular because the single quote character is replaced by latex by a different quote (perhaps because it looks better, i.e. more slanted).
It seems to be fine to copy/paster from the HTML manual though.
