sudo port install xfig

[barron@…]

I am running OS X Yosemite, using Xcode 6.1.1 and just installed Maxports. I am running "sudo port install xfig" in my main directory. I get:

--->  Building tightvnc
Error: org.macports.build for port tightvnc returned: command execution failed
Please see the log file for port tightvnc for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_x11_tightvnc/tightvnc/main.log
Error: Unable to upgrade port: 1
Error rebuilding tightvnc
    while executing

I looked in the log file and I see there are errors from some Makefile. I tried running sudo port clean (as the Macports ticket suggests) but this gives me an error message:

sudo port clean
Can't map the URL 'file://.' to a port description file ("Could not find Portfile in /Users/barron").
Please verify that the directory and portfile syntax are correct.
To use the current port, you must be in a port's directory

I have no idea what a port's directory is...
