brew install zlib throws an error on osx mavericks

I first attempted to install josegonzalez/homebrew-php. It failed at the zlib install. I then tried to just install zlib, and it failed in the very same manner. Below is the error. Any help would be greatly appreciated. ``` Indatuss-MacBook-Pro-7% brew install zlib ==> Downloading http://zlib.net/zlib-1.2.8.tar.gz Already downloaded: /Library/Caches/Homebrew/zlib-1.2.8.tar.gz ==> Patching patching file configure ==> ./configure --prefix=/usr/local/Cellar/zlib/1.2.8 ==> make install make: *** [inflate.o] Error 1 1 error generated. make: *** [trees.o] Error 1 1 error generated. make: *** [deflate.o] Error 1 ``` Not sure what is causing this error, or much less how to fix it.
