user10387: Here are the instructions I have created so far:

Install the necessary dependencies
pacman -S boost boost-libs openssl db base-devel qrencode qt4 automoc4

Clone the GitHub repository:
git clone https://github.com/bitcoin/bitcoin.git
cd bitcoin

Checkout the Git source to the latest release listed at https://github.com/bitcoin/bitcoin/releases:
git checkout v0.8.5

Change to the source directory:
cd src

Compile Bitcoin-Qt from source
qmake-qt4 -makefile -Wall USE_QRCODE=1
make



There are a ton of generic instructions spit out when I enter qmake-qt4 command and then upon entering the make command I am told:

make: * No targets specified and no makefile found.  Stop.

FYI, I am using the PKGBUILD file as a guideline for creating the above instructions.

user9790: Since the build system has moved to Autotools, the method for building Bitcoin-Qt is a bit different. 
git clone https://github.com/bitcoin/bitcoin.git bitcoin
cd bitcoin
git checkout v0.8.5
./autogen.sh 
./configure --with-qt
make -j8
