Getting git-svn installed without root privileges is truly epic, given there are virtually no installation instructions for it, and its homepage seems to be down. This doesn't bode well for git-svn adoption in managed environments like mine where users don't have root. In fairness, the hard bit is Subversion and its perl bindings, but those do need to be current, and the commonly available advice to install Alien::SVN using cpan is totally broken for non-root installs. I hope that the git-svn guys can simplify this down the road...
So, I thought I'd share my solution here to save others the trouble...
###Don't use cpan to install Alien::SVN -- it should have made this whole thing really easy, but it has a number of known bugs when installing without root.###
Here's what worked for me. I have a folder ~/usr for my usual user-local installs, that's already been set up with the usual environment variables in my .bashrc:
export PATH=~/usr/bin:$PATH
export LD_LIBRARY_PATH=~/usr/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=~/usr/lib/pkgconfig:$PKG_CONFIG_PATH
1) Download and install openssl from www.openssl.org/source
tar zvxf openssl-0.9.8i.tar.gz
cd openssl-0.9.8i
./configure --prefix=/home/mdroe/usr
make -j
make install
2) Download subversion tarball
cd ..
tar jxvf subversion-1.5.4.tar.bz2
cd subversion-1.5.4
3) Download neon inside the subversion source tree, and configure
wget http://www.webdav.org/neon/neon-0.27.2.tar.gz
tar zvxf neon-0.27.2.tar.gz
mv neon-0.27.2 neon
cd neon
./configure --prefix=/home/mdroe/usr --without-gssapi --with-ssl=openssl
4) Get apr and apr-util, and configure
svn co http://svn.apache.org/repos/asf/apr/apr/branches/0.9.x apr
cd apr
./buildconf
cd ..
svn co http://svn.apache.org/repos/asf/apr/apr-util/branches/0.9.x apr-util
cd apr-util
./buildconf
cd ..
5) Build subversion
./autogen.sh
./configure --prefix=/home/mdroe/usr --with-ssl --enable-shared
make -j
make install
6) Build perl bindings
make swig-pl
make swig-pl-lib
make install-swig-pl-lib
cd subversion/bindings/swig/perl/native
perl Makefile.PL PREFIX=/home/mdroe/usr
make install
cd ../../../../../..
7) Download, build and install git
tar zvxf get-1.6.0.tar.gz
cd git-1.6.0
./configure --prefix=/home/mdroe/usr
make install
... follow Andrew Straw's git instructions ... (???) ... profit!!!
