wine users - Dec 2010 - trouble compiling and running wine 64-bit on Ubuntu Natty Studio

Hi. 
I have downloaded the git, compiled and installed wine as 64-bit. 
My main executables are 
/usr/local/bin/wine64 and wine64-preloader
But I can't run anything. A "wine" command tells me wine isn't
installed, which I guess it isn't, and "wine64" gives me a
segmentation fault.
Do I need a symlink?

ubuntu$ wine notepad
The program 'wine' can be found in the following packages:
 * wine-bin-unstable
 * wine1.2
 * wine1.0
Try: sudo apt-get install <selected package>
ubuntu:~$ wine64 notepad
Segmentation fault
ubuntu:~$ 

So where
