I hadn't checked that before, but for the last few days there's been a
different failure than the one I saw earlier:

+ERROR:  could not load library "/home/fabien/pg/build-farm-11/buildroot/HEAD/pgsql.build/tmp_install/home/fabien/pg/build-farm-11/buildroot/HEAD/inst/lib/postgresql/llvmjit.so": libLLVMOrcJIT.so.12git: cannot open shared object file: No such file or directory

whereas what I fixed is about:

+ERROR:  could not load library "/home/fabien/pg/build-farm-11/buildroot/HEAD/pgsql.build/tmp_install/home/fabien/pg/build-farm-11/buildroot/HEAD/inst/lib/postgresql/llvmjit.so": /home/fabien/pg/build-farm-11/buildroot/HEAD/pgsql.build/tmp_install/home/fabien/pg/build-farm-11/buildroot/HEAD/inst/lib/postgresql/llvmjit.so: undefined symbol: LLVMInitializeX86Target

Changed somewhere between
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=seawasp&dt=2020-11-20%2009%3A17%3A10
and
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=seawasp&dt=2020-11-21%2023%3A17%3A11

The "no such file" error seems more like a machine local issue to me.

Greetings,
