Failed to build fswatch, when building clamav-server

[Horst B Simon]

Hi 
I getting following errors, when building clamp-server:Error: Failed to build fswatch: command execution failed 

Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_sysutils_fswatch/fswatch/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug.
Error: Processing of port clamav-server failed

It is on macOS High Sierra Version 10.13.6
MacPorts-2.10.5-10.13-HighSierra
Xcode Version 10.1 (10B61)

I couldn’t find anything with google, should I open a ticket?

Regards,
Horst Simon
