PyNaCl Build Failure on Solaris 10: randombytes Test Fails During make check

Question

I am trying to build and install PyNaCl on a Solaris 10 (SunOS 5.10) system, but the process fails during the make check step. The failure occurs in the randombytes test, which results in the overall test suite failing with a non-zero exit status.

Environment:

•   OS: Solaris 10 (SunOS 5.10)
•   Architecture: x86_64
•   GCC Version: 9.5.0
•   Python Version: 3.11
•   PyNaCl Version: 1.4.0
•   libsodium Version: 1.0.18

PASS: aead_aes256gcm
PASS: aead_aes256gcm2
PASS: aead_chacha20poly1305
