Hi Raghav,

I get a nondeterministic build failure in libdecaf:

cd /tmp/guix-build-libdecaf-1.0.drv-0/build/src/generator/curve25519 && /gn=
u/store/iaqmwj2290z5nnrk69bss6r0d9lpr8cs-python2-2.7.16/bin/python2.7 /tmp/=

d --guard=3Dp25519/f_field.h --item=3Dp25519 -o /tmp/guix-build-libdecaf-1.=

    mkdir(name, mode)
OSError: [Errno 17] File exists: '/tmp/guix-build-libdecaf-1.0.drv-0/build/=
src/GENERATED/c/p25519'

It might not support parallel builds properly.

The next attempt did work (without changing anything).
