[ccp4bb] ./configure problem

[A K]

Hi there,
I am trying to install ccp4 on a scientific linux system. I've got stuck in
the step where I need to configure the system. After sourcing ccp4.setup, I
go to the main ccp4 folder and try ./configure help, but I get the error
"bash: ./configure: No such file or directory". It looks as if the
configure script has not been included in my tar file. The file I unzipped
was called ccp4-6.3.0.1-arp-linux-x86_64.tar.gz. Any suggestion is highly
appreciated.
