Oops indeed; fixed in 36f18626a9f8e9ba287e0fd3f1d0400345ca5ee7.
It’s not ‘petsc’ that was affected but rather its variants; they’d lead
to a different derivation every time (!), one that fails to build:
$ ./pre-inst-env guix build -d petsc-openmpi
/gnu/store/lszhaiiyrkbdlldp42hqfhmaxcvqpfq7-petsc-openmpi-3.16.1.drv
$ ./pre-inst-env guix build -d petsc-openmpi
/gnu/store/r2gam9iwv67qvx8hq9sj9rj430qwa31c-petsc-openmpi-3.16.1.drv
$ ./pre-inst-env guix build -d petsc-openmpi
/gnu/store/iw7jkd9dqsfxiz8qij53wdhqg9xzgi5g-petsc-openmpi-3.16.1.drv
Fun. :-)
