    1) You have to install setuptools (it is necessary to run setup.py of your HTSeq).

    Download sources tar.gz setuptools-0.6c11.tar.gz, unpack it, and then do the steps like you installed python2.7, but in the folder where you unpacked setuptools sources:

    ./configure --prefix=/home/amit/tools/localpython 
    make 
    make install
    

    2) When you will install setuptools, a easy_install executable will apear in python2.7/scripts/ folder. You can use it to install packages easily:

    /home/amit/tools/localpython/bin/python2.7/scripts/easy_install HTSeq
    

    it will automatically find the package and will download and install it for you along with all dependencies.

    Setuptools is another requirement which you need to install that package.

    One option is to use virtualenv to create a contained python environment. This can be made everywhere and is owned by the user who creates it.

    To install virtualenv without admin rights (from this answer):

    Download tar.gz of the latest version of virtualenv. Unpack it. You don't even need to install it, just run virtualenv.py, for example:

    wget http://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.7.1.2.tar.gz
    tar -xzf virtualenv-1.7.1.2.tar.gz
    /home/amit/tools/localpython/bin/python2.7 virtualenv-1.7.1.2/virtualenv.py env
    
    env/bin/pip install HTSeq
    env/bin/pip install numpy
    

    Now run your script using the python binary in the virtual environment:

    env/bin/python myscript.py
