py27-scipy: cc1: error: unrecognized command line option "-arch"

[spamaddress.giveaway@…]

I don't think this is a duplicate bug/ticket although I'm not completely positive. These might be related but I don't think so. #37415 #39141

I'm on Mac OS 10.7.5. The upgrade error seems to be related to invalid flags sent to compiler.

My ports are all up to date except for py27-scipy. It won't upgrade. I attached the main.log file. Here is the console message:

--->  Building py27-scipy
Error: org.macports.build for port py27-scipy returned: command execution failed
Please see the log file for port py27-scipy for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_python_py-scipy/py27-scipy/main.log
Error: Unable to upgrade port: 1

MY SYSTEM and PORTS

port outdated

The following installed ports are outdated:
py27-scipy                     0.11.0_0 < 0.12.0_2       

port installed python27

The following ports are currently installed:

  python27 @2.7.3_0+universal
  python27 @2.7.3_1+universal
  python27 @2.7.5_0+universal (active)

I'm not using atlas.

The port for gcc:

gcc45 @4.5.4_6 (active)

The following numpy ports are currently installed:

  py27-numpy @1.6.2_1
  py27-numpy @1.6.2_2
  py27-numpy @1.7.1_0 (active)

I did a clean:

sudo port clean py27-scipy

My current scipy installation appears to be at least partially broken: more than trivial number of test failures. (attached file)
