@yurivict This error is due to the POSIX incompatibility of FreeBSD.

FreeBSD exports a function symbol named timezone, while other
UNIX-like OSs use that symbol to store a current timezone.

I implemented a fix for this issue last month in #2493, so is should
be resolved once the patch gets merged into the main line.
