Checking for existing LLVM tree: found!
Checking sizeof(long): compiling configure test program failed
gcc version 4.4.5 (Ubuntu/Linaro 4.4.4-14ubuntu5)
Would you please gist configure.log.
configuration.log says : no g++ installed
I update my distro with g++ and now the compilation works.
Now, it's my turn to play with rubinius.
Ok great. Let us know how it goes.
