error during sudo port upgrade outdated

[sangshimgm@…]

I got the following error during upgrade.

ShimMBA:~ DanShim$ sudo port upgrade outdated

Error: Unable to open port: can't set "compiler.blacklist": couldn't determine build number of compiler "gcc-4.2"
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets

Then I try to check the version of gcc. It seems fine, I am unsure.

ShimMBA:~ DanShim$ gcc-4.2 -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin14.5.0
Thread model: posix

I reinstalled command line tools but it did not help.

Thanks in advance.

Your "gcc-4.2" is actually clang. That's not normal. On OS X Yosemite, which it appears is what you have, /usr/bin/gcc-4.2 should not exist at all. I'm guessing it is a symlink to clang. If so, remove it.

Replying to ryandesign@…:

Thanks. It solves the problem.
