libgcc@4.9.2_1 build failure

[summeryingl@…]

Hi,

I try to install scipy, which requires installing libgcc. My computer is a mac OS X 10.9.5
I have build failure for libgcc
macports is the latest version

error message:

"Error: org.macports.build for port libgcc returned: command execution failed
Please see the log file for port libgcc for details:
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc49/libgcc/main.log
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets
Error: Processing of port libgcc failed"

Besides the error I also get a warning message:

The Xcode Command Line Tools don't appear to be installed; most ports will likely fail to build.

Thanks
Ying

That log file snippet doesn’t contain any useful information, but this is probably caused by the fact that you don’t have the Command Line Tools installed. Please install them and try again.

% xcode-select --install
% sudo port clean libgcc
