munging readline in analysis

some programs such as IPython and faetures such as command line hcacking require gnu readline. Here is what I did under ubuntu to get it going

1. all this is using the version of python that you use to run analysis (you may need to set the environment variables TCL_LIBRARY etc to get i to work (see $CCPNMR_TOP_DIR/bin/analysis)
2. this is using ccpns own downloaded python
3. change to $CCPNMR_TOP_DIR/python2.4/Python-2.4.2/Modules/
4. edit Setup and uncomment line at about line 160 which reads 'readline readline.c -lreadline -ltermcap'
5. cd to $CCPNMR_TOP_DIR/python2.4/Python-2.4.2
6. run python setup.py install
