make install fails because GNU tar needed

[dev <dev@cor0.com>]

Well I am making progress in that I have what looks like a
successful build.

what fails next on the non-linux world is the next requirement for
GNU tar for some reason :

# gmake CFLAGS="$CFLAGS" LDFLAGS="$LD_OPTIONS" NEEDS_LIBICONV=Yes \
> SHELL_PATH=/usr/local/bin/bash \
> SANE_TOOL_PATH=/usr/local/bin \
> USE_LIBPCRE=1 LIBPCREDIR=/usr/local CURLDIR=/usr/local \
> EXPATDIR=/usr/local NEEDS_LIBINTL_BEFORE_LIBICONV=1 \
> NEEDS_SOCKET=1 NEEDS_RESOLV=1 USE_NSEC=1 \
> PERL_PATH=/usr/local/bin/perl \
> NO_PYTHON=1 DEFAULT_PAGER=/usr/xpg4/bin/more \
> DEFAULT_EDITOR=/usr/local/bin/vim DEFAULT_HELP_FORMAT=man \
> prefix=/usr/local install >
> ../git-2.0.4_SunOS5.10_sparcv9.006.install.log

Well that is maddening.

Is there some magic somewhere to use ordinary POSIX tar ?

Also, what is shnot ?
