After upgrading to OSX 10.9 (Mavericks) from OSX 10.8 (Mountain Lion), Drush broke. I've MAMP.

The error message when I invoke drush:

```
Could not open input file: /usr/lib/php/pear/drush/drush.php

```

I've put the below in .bash\_profile

```
export PATH="/Applications/MAMP/Library/bin:/Applications/MAMP/bin/php5.3.20/bin:$PATH"

```

Any idea?
