Workaround gnutar for gdbm

[Alejandro Imass]

Hi all,

Path to gnu tar seems hardcoded in make procedure for gdbm so here's
how I quickly worked around that problem:

So if you into /usr/bin/gnutar not found whilst upgrading your ports
after Maveriks just install gnu tar from port (sudo port install
gnutar) and then cd /usr/bin and sudo ln -s /opt/local/bin/gnutar .

Hope it helps someone else!

Best,
Alejandro Imass
