Error in compiling fontutils.scm

[Andreas Enge <andreas@enge.fr>]

Right now, the following error occurs when compiling fontconfig.scm:

$ make gnu/packages/fontutils.go

/bin/mkdir -p `dirname "gnu/packages/fontutils.go"` ;                   \
        LC_ALL=C                                                        \
        ./pre-inst-env                                  \
        /usr/bin/guild compile -L "." -L "."    \

It is rather mysterious, since fontconfig has not been changed for over a

Any help would ne appreciated.
