pkg-config doesn't pickup the homebrew pkg-config path

[andyli]

Discovered from our TravisCI build that suddenly fails recently.

In the build, after migrating Homebrew to v0.9.9, the pkg-config path search path is not updated:

$ pkg-config --variable pc_path pkg-config
/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/pkgconfig:/usr/local/Library/ENV/pkgconfig/10.9

where /usr/local/Library/ENV/pkgconfig/10.9 should be /usr/local/Library/Homebrew/os/mac/pkgconfig/10.9.

You need to brew update. This was fixed.

But my build log shows that brew was upgraded to 092d471, which was the most recent commit as of writing.

@andyli It looks like your problem may be here:
https://github.com/andyli/neko/blob/master/.travis.yml#L44-L49

It doesn't upgrade anything but cmake, and the path is hard coded in the pkg-config binary, so you need to at least upgrade pkg-config too, but I'd suggest just making it brew upgrade and see what else is outdated in that image.

Doing brew upgrade pkg-config after brew update fixed it. Thanks!
FYI, I tried brew upgrade too, which worked, but it took too long in TravisCI.

@andyli that's great! Glad you got it working.
