I used the following instructions from Nicholas to compile wkhtmltopdf & wkhtmltoimage
For those installing on Mac OS X 10.6.8, these are the steps I followed to get a successful build:
$ git clone git://gitorious.org/~antialize/qt/antializes-qt.git wkhtmltopdf-qt $ cd wkhtmltopdf-qt $ git checkout staging
Perform a find/replace across all files in the 'wkhtmltopdf-qt' folder (I did this using BBEdit): FIND: MACOSX_DEPLOYMENT_TARGET = 10.4
