Despite my best efforts, I have been unable to get html2 working in RHEL6 due to issues with webkitgtk. The version provided by Red Hat is 1.2.6. Unfortunately, wxWebView requires 1.3.1 or 1.3.2. The actual check in the configure script is 1.3.1, but 1.3.2 is mentioned elsewhere. I’ve tried building nearly every version of webkitgtk from 1.3.1 all the way up to 1.10.2 unsuccessfully.
