Thanks for the s/-/_/ tip! This works :-)

Having that out of the way i noticed that trimesh's testsuite dependes
(for whatever reason) on a javascript library which has to be generated
via npm, which is currently not available in Guix. Therefore i disabled
the testsuite from trimesh.

Attached is a corresponding patch.
