Comment (by braumann@…):

 Well, may I ask if what compiler you are expecting to be used for building
 `julia`? `gcc5`?

 For me I had to specify this using the `configure.compiler` switch in the
 command line.

 Then I got beyond the point where it stopped above. Since in
 `debuginfo.cpp` the function `strndup` is being used (was not provided in
 10.6.8) I put an own definition of `strndup` (as is being done in many
 ports via patches) into `debuginfo.cpp`.

 The problem I could not solve happened later, during linking `libjulia-
 debug.dylib`. Lots of LLVM related symbols could not be resolved. This is
 strange, as `USE_SYSTEM_LLVM=1` and `LLVM_CONFIG=llvm-config-mp-3.7`
 should guide the linking process to the correct libraries. However, I
 suspect, nevertheless it still tries to use Xcode-related libraries (which
 should be no problem with a modern Xcode), but this is not fully clear, as
 no paths are being printed in the log file.

 Thanks for comments.
