In principle, you need to report this problem to the people who maintain your ROOT binary distribution.

In the meantime, you could try a “brutal fix”.
Download a ROOT binary distribution (use the same ROOT version as yours) provided by the ROOT Team for some Linux version, unpack it somewhere, and then copy all “root/etc/plugins/ROOT@@*” directories into your “plugins” directory.

Many thanks for your patience in diagnosing the problem. The problem indeed seems to be an omission in the FreeBSD port of root, which I will report to the maintainer. Your suggested fix worked.

Thanks again,
