"yum update" for the past few days has had the following problem: --> Running transaction check --> Processing Dependency: libwebkit-1.0.so.1()(64bit) for package: gimp-help-browser ---> Package WebKit-gtk.x86_64 0:1.1.1-1.fc11 set to be updated --> Finished Dependency Resolution 2:gimp-help-browser-2.6.5-2.fc11.x86_64 from installed has depsolving problems --> Missing Dependency: libwebkit-1.0.so.1()(64bit) is needed by package 2:gimp-help-browser-2.6.5-2.fc11.x86_64 (installed) Error: Missing Dependency: libwebkit-1.0.so.1()(64bit) is needed by package 2:gimp-help-browser-2.6.5-2.fc11.x86_64 (installed)
This is fixed in gimp-devel-2.6.5-3.fc11 which is available in Rawhide, perhaps your mirror is out of date?
That does indeed seem to have been the problem; a retry with a fresher mirror took everything with no issues. Sorry about the bother!
