[webkit-gtk] Problem building webkitgtk 2.4.5

[David Ronis]

I'm trying to build gnome-3.16.1 on a laptop running Slackware Linux; I
have already built and installed 2.8.1 (relatively painlessly it turns 
out).  Unfortunately, the gnome folks haven't updated many things to 
use this API (e.g., yelp or evolution) and I have to build/install an 
earlier version of webkitgtk.

I'm currently trying to build 2.4.5. The build fails because 
apparently GMutexLocker is ambiguous (the log follows below).

Thanks in advance
