libwebp4 will not build when there are other OpenGLs on OS X. It "knows" that 
OS X only has OpenGL.framework and having freeglut installed confuses it. I 
don't see an easy way to get configure to not screw this up so I added a 
BuildConflicts on freeglut to libwebp4 so fink will automatically remove 
"freeglut" but not "freeglut-shlibs" when building libwebp4 and will reinstall 
it afterward.
