How can I just tell pango where to look for fonts?

To fix:

(grafit:31327): Pango-WARNING **: failed to choose a font, expect ugly
output. engine-type='PangoRenderFc', script='latin'

(grafit:31327): Pango-WARNING **: failed to choose a font, expect ugly
output. engine-type='PangoRenderFc', script='common'

(grafit:31327): Pango-CRITICAL **: _pango_cairo_font_map_get_renderer:
assertion `PANGO_IS_CAIRO_FONT_MAP (fontmap)' failed


pango-querymodules gives:
