py26-scipy build error due to numpy

[dominikfriese@…]

For the last few weeks I wasn't able to install any new ports because the py26-scipy package is doing stange things. Whenever I try to upgrade it I receive the following message:

[Users/domi] > upgrade py26-scipy
--->  Computing dependencies for py26-numpy
--->  Cleaning py26-numpy
--->  Computing dependencies for py26-scipy
--->  Building py26-scipy
Error: org.macports.build for port py26-scipy returned: command execution failed
Please see the log file for port py26-scipy for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_python_py-scipy/py26-scipy/main.log
Error: Unable to upgrade port: 1
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets

What is wrong with my ports?

Please ​clean and try again and attach the main.log file.

Same error after clean py26-scipy.

Actual error is:
