Thanks to Jim and Kevin for their comments.

Following Kevin's suggestion I now have the following system:

1) redhat 7.0.
2) upgraded compiler from Redhat (using up2date) to gcc-2.96.85 (and g77 etc)
3) installed gcc(etc) 3.0 in /usr/local/bin this was straight forward as
Kevin suggests above

following this I had a clean distribution of CCP4 4.1.1. I configured as
.../configure --with-x linux

then edited $CCP4/config.status and changed
FC to /usr/local/bin/f77 and
CC to /usr/local/bin/gcc

ran config.status (NB no change to optimization level)

make and make install of the suite.......

ran the $CEXAM/unix/runnable/run-all script.....

AND IT ALL WORKED! again I hasten to add that the programs ran and didn't
crash (so I'm assuming they gave sensible answeres).....

so in summary this probably isn't the best way to have your linux box set
up but it does at least give a working compiled version of CCP4 for redhat
7* boxes.

I hope this helps. if the demand is really there I will make a web page
(or kevin might update his) with detailed instructions. Though my real
current recomendation is - stick with RedHat 6.2
