Most likely the build is using a non-MSYS Perl install.

That's probably due to the failed generaion of llvm-config
above. llvm-config is an script used for determining library
dependencies and is used by the configure&make build. At some point on
the build a tool determines the mutual dependencies among the multiple
LLVM libraries and that information is embedded on llvm-config.
