I suspect this define here. Firstly, it should be outside the
operating-system record. Here it means a field named 'define' which is
clearly not intended. The %my-gnome at the end will also cause problems
later as now %my-gnome is defined as a package record (that is not
stored anywhere) and as %my-gnome, which will cause nonterminating and
useless recursion. You might also have to import (guix packages) to
construct package records.

PS. Your email client adds empty rows between every row of text, which
makes it hard to read. If there is a setting to control that or to omit
the HTML part completely (I'm assuming the problem is caused by
converting HTML-first emails to text form), you could try to turn it
off.
