geos-3.3.1_0 is failing to build on Snow Leopard with Xcode-4.0.2 with the following:

Seems to be the same as #30309, but I'm building 3.3.1 on Snow Leopard.

In #30309 I fixed geos to use gcc-4.2 instead of llvm-gcc-4.2 or clang. In r87289 vince updated the port to 3.3.1 and removed what I added, because 3.3.1 allegedly supports clang. But maybe he didn't test llvm-gcc-4.2. Please try clang instead of llvm-gcc-4.2. If that doesn't work, please try gcc-4.2.

Ooops, sorry. You’re right Ryan, I didn’t bother testing with llvm-gcc. Clang works fine: successful Clang compilation was indeed a primary goal of this new release. If it works, then we can maybe patch the Portfile to force the use of clang instead of llvm-gcc.

[skymoo (Adam Mercer)]

Building with clang, i.e. using

sudo port -us upgrade geos configure.compiler=clang

results in a successful build.
