srfi-1 is included per default, no need to do it again

Above will fail as soon as accented letters etc are used:
\markup \alternate-colors #'("red" "blue" "green") "trööt"
->
(process:6915): Pango-WARNING **: Invalid UTF-8 string passed to
pango_layout_set_text()

warning: no glyph for character U+FFFD in font
`/home/hermann/.local/share/fonts/C059-Roman.otf'

This is due to guile-1 limitations.
Some where there is some code around it, but I hate caring about this
special problem.
With Jonas' experimental guile-2-build it works shamelessly.
My strongest argument to switch to guile-2 for good.
