Failed installation of LDC

[LDC_Installer via digitalmars-d-ldc]

Hi there, I've followed exactly the "how to install LDC" guide on 
the dlang.org download page. LLVM 3.7.1 is installed with target 
being x64. Then I've downloaded ldc and updated the submodules. 
Next step was the call to "cmake -DLIB_SUFFIX=64 .." in the build 
directory, followed by "make". This is the error message I get:

/home/username/Downloads/ldc/driver/linker.cpp: At global scope:
/home/username/Downloads/ldc/driver/linker.cpp:35:13: warning: 
‘bool endsWith(const string&, const string&)’ defined but not 
used [-Wunused-function]
  static bool endsWith(const std::string &str, const std::string 
&end) {
              ^
make[2]: *** [CMakeFiles/LDCShared.dir/driver/linker.cpp.o] 
Fehler 1
make[1]: *** [CMakeFiles/LDCShared.dir/all] Fehler 2
make: *** [all] Fehler 2

Also, I've got DMD v2.071.0 installed.
Any suggestions how to resolve this?
