libgcc @4.9.2_1 Error: Processing of port libgcc failed - libgomp

[Andrew_Rogers@…]

I recently attempted to upgrade my MacPorts and Xcode. However, I ran into issues when MacPorts attempted to update ports that depend on libgcc. I decided to start from scratch and did an uninstall/fresh install of Xcode, command-line tools, and macports but I am still getting the same error (see below) building the port.

It looks like the build is failing due to an issue with libgomp trying to use clock_gettime and etc.. I'm stuck on this and not sure what is going wrong. I would be grateful for any suggestions.

Thanks, -Andy

OSX version: 10.9.5 Xcode version: 6.1.1 MacPorts version: 2.3.3
