New issue 573: The install script breaks if CC is set to a full path on OS X
https://bitbucket.org/yt_analysis/yt/issue/573/the-install-script-breaks-if-cc-is-set-to

Nathan Goldbaum:

If someone sets CC to be a full path:


```
#!bash

export CC=/usr/bin/gcc
```

The install script will fail due to an invocation of sed:


```
#!bash

Installing BZLIB
sed: 1: "s/CC=gcc/CC=/usr/bin/gcc/
": bad flag in substitute command: 'u'

This could be fixed by using `|` as a delimiter instead of `\` in the sed call.  This appears to not be an issue on linux, so I think this is a problem with BSD sed versus GNU sed.
