Comment (by mojca):

 I did not manage to reproduce this at the moment, but here are some
 difference. This is what I get (10.13):
 {{{
 checking for WEBKIT... configure: WARNING: webkit2gtk not found, falling
 back to webkitgtk
 checking for WEBKIT... configure: WARNING: webkitgtk not found.
 configure: WARNING: WebKit not available, disabling wxWebView
 }}}
 and this is what's in your log:
 {{{
 checking for WEBKIT... yes
 }}}
 I believe the difference comes from one of the `webkit-gtk` ports being
 installed or not. This needs fixing in any case, but it would be nice to
 figure out the source of the problem as well.
