Gene Cluster is a program for clustering. I wanted to use it to analyse gene expression data. However, I had problems during installation under Ubuntu 14.04. This is how I solved it:

# install dependencies: Motif libraries
sudo apt-get install libxext-dev libmotif-dev

Get GeneCluster3.0 source code and unpack it.

# configure to install in local dir
./configure --prefix=`pwd` --program-prefix=gene_ && make && make install

# add install dir to ~/.bashrc
