--- Update NASM ---
Download Nasm 2.10.05 for mac here: http://www.nasm.us/pub/nasm/releasebuilds/2.10.05/macosx/

From where I downloaded the file

nasm-2.10.05-macosx.zip

Unzipping this file resulted in a directory named nasm-2.10.05 being created.

check current version: 

$ nasm -v

NASM version 0.98.40 (Apple Computer, Inc. build 11) compiled on Aug 4 2012

move to nasm-2.10.05 folder:

check version:

./nasm -v
NASM version 2.10.05 compiled on Sep 9 2012

I decided to put the downloaded nasm in a directory called prog/nasm inside my home directory. I moved it there using

mkdir -p ~/prog/nasm
mv * ~/prog/nasm

I then added the following changes

export PATH=~/prog/nasm:$PATH

to my setup script, where I also set up other environment variables. After having rerun the setup script I could use the downloaded nasm, after first having verified that it was found using

$ nasm -v
NASM version 2.10.05 compiled on Sep 9 2012
