     That's libpng-1.6.28, right? I've tried to reproduce the failure on cu=
rrent
     'core-updates' master (x86_64-linux). It builds just fine:
    =20
     $ git describe
     v0.12.0-2306-gf826c8c7e
    =20
     $ ./pre-inst-env guix build libpng --check --no-grafts -K
     /gnu/store/vis7x2j2lsmwbl5m5w794c23ysqah8xh-libpng-1.6.28
    =20
     At a glance source code of libpng and it's tests does not contain any =
pthread calls.
    =20
     Do you have a build log with the failure? I wonder where missing symbo=
ls come from.
    =20

Yes *IT* builds fine.  It's just the thing that depend upon it that don't.
For example look at the most recent build attempt for pspp.
