duplicate symbol error while compiling libgcrypt 1.5

[David Reiser]

I'm trying to build version 1.5 in Mac OS X 10.7 using clang. The build stops with:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is this error likely to be specific only to clang? Is there a straightforward solution?
