Ok, well maybe try building
/gnu/store/g9xfx06xs21jnrsg7h42m5ggfg2zfdfg-texlive-hyphen-complete-66594-checkout.drv
and post the log.

Since quite recently, the subversion downloads should fallback to
talking to bordeaux.guix.gnu.org, which should be able to provide a nar
for this, even if you get a 404 from www.tug.org, but it would be good
to see if that is attempted.
