We've been trying to get WebKit working inside of jhbuild on FreeBSD. First step was to try to get current trunk building correctly. This bug will depend on the issues that we've found so far.
All bugs appear to have been fixed and merged to the 2.4 branch. I'll do a test soon to make sure everything is really OK before the .91 release and then I'll close this bug.
Thanks very much!
Building the branch works without further patching. Let's say this one is closed.
