Deploying my inpainting code on other machines

It's quite a mess, since I have limited permissions on each of them, and their environments vary. Also, no git.
required:
wget
python (developed on 2.6.5)
First, I need pyfits:
mkdir python
cd python
wget http://pypi.python.org/packages/source/p/pyfits/pyfits-3.1.tar.gz
Second, pyfits need setuptools:

wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg#md5=fe1f997bc722265116870bc7919059ea
I want to install to a custom location (the ./python directory tree), hence I have to create directory trees for both of them:
mkdirhier [ABSOLUTE PATH TO]/python/lib/python2.7/site-packages/
mkdirhier [ABSOLUTE PATH TO]/python/lib64/python2.7/site-packages/

The .bashrc file's PYTHONPATH variable must be adjusted:
vi ~/.bashrc
export PYTHONPATH=[ABSOLUTE PATH TO]/python/lib/python2.7/site-packages:[ABSOLUTE PATH TO]/python/lib64/python2.7/site-packages/
Do not forget to restart bash:
bash
Then, installing setuptools:
sh setuptools-0.6c11-py2.7.egg --prefix='[PATH TO]/python'
python setup.py install --prefix='[PATH TO]/python'

The file structure:
../growth-curve-photometry/
../data/SDSS/u/ #griz
../data/MASKS/
../data/maskFilenames.csv
../data/maskFilenames.csv
../data/SDSS_photo_match.csv
../data/CALIFA_mother_simple.csv
../data/filled_u #griz

I need AstLib as well:
wget http://downloads.sourceforge.net/project/astlib/astlib/0.6.1/astLib-0.6.1.tar.gz?r=http%3A%2F%2Fastlib.sourceforge.net%2F&ts=1348484024&use_mirror=switch
tar -xvzj astLib-0.6.1.tar.gz
cd astLib
python setup.py install --prefix='[PATH TO]/python/'

...and all the hell breaks loose here, because my home is mounted across the network, hence $PYTHONPATH points to a couple of different Python versions. Separate ~.bashrc.$HOSTNAME files worked: http://askubuntu.com/questions/15618/repercussions-to-sharing-bashrc-across-machines-with-dropbox.
Then fill.py should be edited, or even copied to allow several different processes work in different bands and galaxy sample slices.
