[xcrysden] XCrysDen installation

[azzizuc at libero.it]

Dear everybody,
I am a new member of this mailinglist. Nice to meet you!

I am writing because I need some help about XCrysDen installation. I am using 
Ubuntu 9.10 64bit and I downloaded xc-1.5.21-linux_x86_64-shared.tar.gz. I 
tried to start the istallation with ./xcConfigure but it wrote: 

   Specify CRYSTAL's crystal module (default: -p: not found crystal: not 
found):  

   WARNING: file -p: not found crystal: not found is not executable !!!

   Specify CRYSTAL's properties module (default: -p: not found properties: not 
found):  

   WARNING: file -p: not found properties: not found is not executable !!!

The problem is that I actually have Crystal and Properties executables and I 
tried also to put these two on the same directory as XCrysDen has been 
downloaded but the problem is still there.

How can I do? How can I check for the correct mobule of Crystal and 
Properties?

Thanks a lot
Regards

Azzurra
