liblas: build failure

[kevinecahill@…]

I upgraded to Sierra and installed the Xcode stuff. The command

sudo port upgrade outdated

failed at this point:

--->  Computing dependencies for liblas
--->  Building liblas
Error: org.macports.build for port liblas returned: command execution failed
Please see the log file for port liblas for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_gis_liblas/liblas/main.log
Error: Unable to upgrade port: 1
To report a bug, follow the instructions in the guide:

This log is not clean. Please run sudo port clean liblas, try building again, and attach the new log if it fails.
