[Macario, Gianpaolo] Thanks for your reply.

Unfortunately it looks to me that the `--prefix=xxx` option provided to configure will be hardcoded to the path returned by 'git --exec-path', and I do not see how this may actually be made dependent on the directory where the binary tarball will be extracted.

How should I configure/make git to have `<install_path>/bin/git --exec-path` return a path which depends on `<install_path>` rather than what provided to `./configure` ?

I tried the following

    $ mkdir -p ~/tmp
    $ cd ~/tmp
    $ wget http://kernel.org/pub/software/scm/git/git-2.3.5.tar.gz
    $ tar -xvzf git-2.3.5.tar.gz
    $ cd git-2.3.5
    $ ./configure --prefix= \
    --with-curl --with-openssl --without-tcltk \
    CFLAGS="${CFLAGS} `pkg-config --static --libs libcurl`"
    $ make
    $ make DESTDIR=/var/tmp/gittt install
    $ cd /var/tmp/gittt
    $ tar -cvzf ~/git-install-2.3.5.tar.gz .
    $ cd
    $ rm -rf ~/tmp/git-2.3.5
    $ rm -rf /var/tmp/gittt

then extracted the tarball

    $ sudo mkdir -p /opt/tools
    $ sudo chown $USER /opt/tools
    $ cd /opt/tools
    $ tar -xvzf ~/git-install-2.3.5.tar.gz

This is the result when executing

    $ /opt/tools/bin/git --exec-path
    /libexec/git-core

I wanted to have it return `/opt/tools/libexec/git-core` instead.

If I do not specify any `--prefix=xxx` when running `./configure`, this defaults to `/usr/local` which is not good either.

Thanks in advance, and apologies if I am doing something stupid...
