 Here: /opt/local/libexec/llvm-3.1/lib/libLLVM-3.1svn.dylib

 Macports must have put it there, I don't know how to check which variant
 exactly and why.

 I don't think I have other llvm and clang installations besides the ones
 from Apple and Macports.
 But I might have trief to build llvm by hand a year ago and simply don't
 remember anymore.

 I'll try what you suggest. Thanks!
