this error means you are trying to use a psol library built on an older glibc.
(for example, the psol library is built on ubuntu focal or bionic, you are using ubuntu jammy).
On newer glibc they removed pthread_mutex_consistent_np and sys_siglist functions

#1743

I cooked some build instructions in #1760
