 development environments.  To create a new environment for Numba development:
 
 ```bash
-    $ conda create -p ~/dev/mynumba python numpy cython llvmpy llvmmath nose meta
+    $ conda create -p ~/dev/mynumba python numpy llvmpy
 ```
 
 To select the installed version, append "=VERSION" to the package name,
 where, "VERSION" is the version number.  For example:
 
 ```bash
-    $ conda create -p ~/dev/mynumba python=2.7 numpy=1.6 cython llvmpy llvmmath  nose meta
+    $ conda create -p ~/dev/mynumba python=2.7 numpy=1.6 llvmpy
 ```
 
 to use Python 2.7 and Numpy 1.6.
