Installing Tokyo Tyrant on Ubuntu 9.04 (Jaunty), in custom folders/directories

Tokyo Cabinet - first install this
-------------
cd /usr/local/src/
wget http://tokyocabinet.sourceforge.net/tokyocabinet-1.4.21.tar.gz
tar xvf tokyocabinet-1.4.21.tar.gz
cd tokyocabinet-1.4.21
apt-get install zlib1g-dev
apt-get install libbz2-dev
mkdir /usr/local/tokyocabinet-1.4.21/
./configure --prefix=/usr/local/tokyocabinet-1.4.21/
make
make install

Tokyo Tyrant
------------
cd /usr/local/src/
wget http://tokyocabinet.sourceforge.net/tyrantpkg/tokyotyrant-1.1.27.tar.gz
tar xvf tokyotyrant-1.1.27.tar.gz
cd tokyotyrant-1.1.27
mkdir /usr/local/tokyotyrant-1.1.27
./configure --prefix=/usr/local/tokyotyrant-1.1.27/ --with-tc=/usr/local/tokyocabinet-1.4.21/
make
make install

Fix lib problem
------------
cd /usr/local/tokyotyrant-1.1.27/bin/
./ttserver

You will get this error: ./ttserver: error while loading shared libraries: libtokyocabinet.so.8: cannot open shared object file: No such file or directory

To fix it,
cd /usr/local/tokyotyrant-1.1.27/
ln -s /usr/local/tokyocabinet-1.4.21/lib/libtokyocabinet.so.8 lib/
./bin/ttserver will now work
