Been following the steps as described for building the binary trees.
It does not produce a "Calpont" directory as stated in the documentation.

My steps are as follows:
yum groupinstall "Development Tools" (installed)
yum install zlib-devel (installed)
yum install ncurses-devel (installed)
yum install libxml2-devel (installed)
yum install expect (installed)
yum install readline-devel (installed)
cd $HOME
mkdir infinidb-src
cd infinidb-src
wget -Omysql-4.6.2-1.tar.gz https://github.com/infinidb/mysql/archive/4.6.2-1.tar.gz
tar -zxf mysql-4.6.2-1.tar.gz
ln -s mysql-4.6.2-1 mysql
cd mysql
./configure --prefix=$HOME/infinidb/mysql
make
make install
cd ..
wget -Oinfinidb-4.6.2-1.tar.gz https://github.com/infinidb/infinidb/archive/4.6.2-1.tar.gz
tar -zxf infinidb-4.6.2-1.tar.gz
ln -s infinidb-4.6.2-1 infinidb
cd infinidb
./configure --prefix=$HOME/infinidb
make
make install
