ncarg @6.3.0: ncl did not get built

[CLynchy (Cary Lynch)]

Hello! I am trying to install ncarg-6.3.0 for Mac OSX version 10.11.1. Log file is attached, but this is the last bit in the log file:

:info:build Finished making <Build>.
:info:build make: Leaving directory `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_science_ncarg/ncarg/work/ncl_ncarg-6.3.0'

I built ncarg using gcc5 on Mavericks before the recent gcc5 update. The just tried it again and get the same error:

:info:build vtcudr.f:1:0:
:info:build 
:info:build        SUBROUTINE VTCUDR (UCRV,VCRV,WCRV,CCRV,NCRV,ICOL,IARH,IAMA,RT

:info:build gfortran-mp-5: internal compiler error: Abort trap: 6 (program f951)
:info:build Please submit a full bug report,

This appears to be a gcc5 regression, so I filed a bug report upstream as ​https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69013

Upstream ​http://mailman.ucar.edu/pipermail/ncl-install/2015-December/001955.html reports success building ncl-6.3.0 with gcc-5.3.0. The gcc5 bug probably depends on the choice of flags, so it could be useful to examine this build.

Meanwhile, upstream gcc indicates the bug is fixed in recent gcc6, so I tried that. vtcudr.f compiles with gcc6, but then hits a small glitch:

:info:build lex.yy.c:1945:21: error: C++ style comments are not allowed in ISO C
90
:info:build    num_to_alloc = 1; // After all that talk, this was set to 1 anyways...

Adding "configure.cflags -std=gnu11" to the Portfile and building with "+gcc6" seems to work.
