>Description:

On an up-tp-date FreeBSD-current,

% uname -a
FreeBSD troutmask.apl.washington.edu 11.0-CURRENT FreeBSD 11.0-CURRENT #0

where all remnants of base gcc have been removed via 'make delete-old delete-old-libs'

Installation of octave and octave-forge-netcdf and octave-forge-octcdf leads to a 
clash of libc++ API.

% octave
octave:1> pkg load netcdf
octave:2> test_netcdf
error: import_netcdf: /usr/local/lib/octave/packages/netcdf-1.0.1/amd64-portbld-freebsd11.0-api-v49+/__netcdf__.oct: failed to load: /usr/local/lib/octave/packages/netcdf-1.0.1/amd64-portbld-freebsd11.0-api-v49+/__netcdf__.oct: Undefined symbol "_ZNK5ArrayISsE17resize_fill_valueEv"
error: called from:

error:   /usr/local/share/octave/packages/netcdf-1.0.1/test_netcdf.m at line 6, column 1

Clearly, _ZNK5ArrayISsE17resize_fill_valueEv is a name-mangled entity.  So, lets look at ldd output.

% ldd ./netcdf.oct

        libc.so.7 => /lib/libc.so.7 (0x2020bc000)

Whoops.  octave-forge-netcdf was built with /usr/local/bin/g++46.

>How-To-Repeat:

Install freebsd-current
Install octave
Install octave-forge-netcdf
