py27-matplotlib @ 2.3.4 build failure command execution failed

[tim.bauer@…]

Hi there,

I'm quite new to packages and everything around but I'm currently trying to install py27-matplotlib. It returns: Error: org.macports.build for port py27-matplotlib returned: command execution failed

I am running OSX 10.11.5 and Xcode 6.4 with command line tools.

Cleaned and retried several times but produces the same error

here the last lines of the log where the error seems to appear:

SOLVED: Updated Xcode no problems anymore. Sorry for bothering you!
