sshpass build fails at configuration step

--->  Configuring sshpass
Error: Failed to configure sshpass, consult /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_sysutils_sshpass/sshpass/work/sshpass-1.06/config.log
Error: Failed to configure sshpass: configure failure: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_sysutils_sshpass/sshpass/main.log for details.

But if you go to the build directory and run

sudo ./configure --prefix=/opt/local

it will succeeded.

config.log resulted by manual execution of sudo ./configure --prefix=/opt/local

Fixed by reinstalling CLT from scratch & removing port build directory.

Ok. Remember to keep your CLT and Xcode updated in the future.
