This is quite strange. lang/gcc does not provide any of those libraries.
lang/gcc is a metapackage, the only thing it does is depend on the
lang/gccXX you asked for, and it provide symlinks:

# pkg info -l lang/gcc
gcc-5.4.0_2:
        /usr/local/bin/g++
        /usr/local/bin/gcc
        /usr/local/bin/gfortran
# ls -l $(pkg info -ql lang/gcc)
lrwxr-xr-x  1 root  wheel  4 29 mai   15:21 /usr/local/bin/g++@ -> g++5
lrwxr-xr-x  1 root  wheel  4 29 mai   15:21 /usr/local/bin/gcc@ -> gcc5
lrwxr-xr-x  1 root  wheel  9 29 mai   15:21 /usr/local/bin/gfortran@ ->
gfortran5
