Ruby Build 2.1.9 on HP-UX

Hi,
Has someone been able to build ruby on HP-UX?

I am trying to build ruby 2.1.9 on HP-UX:
CFLAGS=“-mt -g +DD64”

Ruby build is giving the below error:

./tool/mkconfig.rb:11: [BUG] Segmentation fault at 0xffffffffffffffe9
ruby 2.1.9p490 (2016-03-30 revision 54437) [ia64-hpux11.31]

sh: 14751 Abort(coredump)
*** Error exit code 134

However, Ruby behaves differently upon setting the below to 6 in
compile.c
#define CPDEBUG 6

The error then is:

[compile step: finish]

Please can you check and suggest ways to get around this. I will be
happy to share more information if needed.
