OS X 10.7:

With libwebp-0.1.3 installed and configuring with '--with-webp', 6.8.3-5 fails compiling with this error:

make[2]: *** [coders/coders_webp_la-webp.lo] Error 1
I'm currently not able to install the latest libwebp-0.2.1, but a glance through the source code suggests that the above errors would not happen with libwebp-0.2.1 where those items are declared (they are not in the 0.1.3 source). The webp configure check needs to make sure that the present webp is good enough for IM rather than just checking for the presence of a single header and generic symbol.
